PVC in the process of processing due to the role of shear force will remove hydrogen chloride to form free and peroxy free radicals and cause degradation, and its degradation shows the corresponding characteristic color. In order to effectively inhibit the degradation of product color and mechanical properties caused by this degradation, the heat stabilizer has become an indispensable main auxiliary agent for PVC processing, in the PVC processing process it can reduce or delay the generation of hydrogen chloride by replacing unstable chlorine atoms, neutralizing hydrogen chloride and eliminating or inhibiting free radicals in the process. With the rapid development of the PVC industry, the market demand for heat stabilizers has also increased significantly. However, due to the level of economic development and other reasons, Many countries have long mainly used lead salt heat stabilizer, according to statistics, so far in PVC heat stabilizer accounted for about two-thirds, while non-toxic heat stabilizer less than 15%. Lead salt heat stabilizer has always been the main variety of PVC heat stabilizer because of its excellent thermal stability and low price. However, research has found that lead salt, as a harmful metal compound, is easy to be extracted from PVC products by water and bath agents, thus entering the human body through various ways to cause harm. Lead is a typical multi-affinity pendant, which has accumulation in the body, can form basophobic lead in the blood, and exists in the skeleton in a stable form, and has toxic effects on various tissues. Therefore, in recent years, a series of relevant policies have been introduced to restrict the use of heavy metals such as lead. As one of the many calcium and zinc stabilizer manufacturers in China, Homart Technology has a strong production capacity and advanced production technology, can produce a variety of specifications of calcium and zinc stabilizer. Ca-Zn Stabilizer designed by Homart technical team not only include calcium salt, zinc salt, antioxidant but also added coupling agent. So, it is have excellent initial coloring performance, good lubricity and weather resistance which can improve the outdoor use effect of the product, Its coupling agent can promote the mixing materials uniform plasticization and improve the smooth surface and reduce production cost. It is believed that with the development of times and technology, calcium and zinc stabilizers will be more and more widely used

With the rapid development of the construction industry, SPC floor has been favored by more and more builders because of its superior performance. The production of SPC flooring seems simple, but the production of high-quality SPC flooring is still challenging.The toughness and hardness of SPC floor are the basic conditions for judging SPC quality. In order to obtain high-quality SPC flooring, these two points need to be considered at the same time. Traditional SPC flooring production uses a mix of CPE135A and ACR to achieve a balance between toughness and hardness, but often because of the different content of these two products, the balance is difficult to achieve,therefore, the SPC floor produced is often unsatisfactory. To solve this production problem, Homart Technology has developed a new SPC floor additive CM-505. CM-505 is a new technological product upgraded and synthesized on the basis of CM-85, it has better and faster plasticizing properties than ACR with strong interfacial adhesion between CaCO3 particles and PVC resin in order to promote CaCO3 and PVC resin can fully fused together. In addition, It has balance impact strength and toughness property for SPC Floor, the toughness not only can be adjusted freely but also will not influence thermal deformation, dimensional stability and warpage of the SPC Floor. CM-505 completely replaces CPE135A and ACR with less dosage and lower cost, it greatly improves the quality of SPC flooring and is easy to use. The advent of CM-505 will help the production of SPC flooring all over the world.

PVC heat stabilizers are additives used in the production of polyvinyl chloride (PVC) to prevent the material from degrading when exposed to high temperatures. PVC is a widely used thermoplastic material that can become unstable and degrade when heated, resulting in discoloration, loss of mechanical properties, and reduced lifespan.They are used in wires and cables, windows, and technical profiles to enhance their heat sensitivity, lubrication, flexibility, durability, and strength. They are also used in various types of pipes, such as soil and sewer, foam core, pressure, corrugated, land drainage, and cable ducting, to increase resistance against chemical attacks. At present, several types of PVC stabilizers are available, which includes lead, tin, organic, and mixed metal.

Polyvinyl chloride (PVC) is a versatile and economically priced thermoplastic, the most versatile of the plastics family, and suitable for almost all areas of human activity. Without PVC additives, PVC might not be a particularly useful substance, but PVC's compatibility with a variety of additives (softening, coloring, making it easier to work with, or making it more durable) gives it a wide range of potential applications, from automotive chassis seals and flexible roofing membranes to pipe and window profiles. PVC products can be rigid or flexible, transparent or opaque, colored or black-and-white, insulating or electrically conductive.There is not just one type of PVC product, but a full range of products tailored to meet the needs of a variety of applications. Unlike most other thermoplastics, most PVC products have a long service life, typically between 10 and 100 years. This requires a highly durable product, and stabilizers play an important role in achieving this performance. All polymers require stabilizers in one form or another, and PVC is no exception in this regard. Before PVC can be made into products, it has to be combined with a range of special additives. The essential additives for all PVC materials are stabilisers and lubricants; in the case of flexible PVC, plasticisers are also incorporated. Other additives which may be used include fillers, processing aids, impact modifiers and pigments. Additives will influence or determine the mechanical properties, light and thermal stability, colour, clarity and electrical properties of the product. Once the additives have been selected, they are mixed with the polymer in a process called compounding. One method uses an intensive high-speed mixer that intimately blends all the ingredients. The result is a powder, known as a `dry blend`, which is then fed into the processing equipment. The second method is to blend the ingredients in either a low or high-speed mixer and then transfer the powder to a melt compounder. This can either be a compounding extruder, or other special equipment for making PVC compounds. These produce a melt which, when cool, is cut into granules ready for processing. In a specialised process, liquid compounds known as plastisols, are produced as dispersions of very fine PVC polymer particles in liquid organic media. PVC compounds are made into products using a variety of processing methods which include extrusion, injection moulding, blow moulding, calendering, spreading and coating. The selection of PVC additives has a great impact on the quality, production cost and efficiency of PVC products.

CPE is made from high-density polyethylene,it is a saturated polymer material, the appearance of white powder, non-toxic and tasteless,it is also the main PVC impact modifier with double performance of the plastic and rubber. It can effectively improve toughness and impact resistance and anti-aging of rigid PVC products, to increase the melting point of PVC. Excellent performance as a result of the above,CPE is widely used in PVC plastic profile, sheet, pipe, pipe fittings, waterproof material, wire and cable jacket, seals and PVC plastic. However, for some products with high hardness requirements, such as SPC floor, wall panel, ceiling, etc., the performance of CPE is slightly insufficient. In order to solve this problem, Homart Technology launched a new product CM-85.CM-85 is a design alternative based on CPE135A performance defects. It is a high-performance material developed by nano-polymerization compound technology. CM-85 is an interpenetrating network copolymer(IPN) with the structure of CPE grafted polyacrylate, its main function is to enhance the impact strength of PVC finished products under low temperature and to promote the fusion property of PVC blend. It is believed that with the application of CM-85, more and more PVC product manufacturers will benefit from it.

PVC plastic is a kind of multi-component plastics. Different additives can be added according to different uses. Because of different components, PVC products show different physical and mechanical properties and are applied in different occasions. Therefore, the selection of high-quality additives is important for PVC production. Hengshui Homart Technology Co.,Ltd was founded in 1999, specialize in PVC Additive research and quality production.

When PVC is heated to 170-180°C, chlorine and hydrogen in the molecules are eliminated and release of hydrogen chloride becomes evident. Once such decomposition starts, unstable structures are formed in the molecule, which further accelerate HCl elimination and decomposition. As PVC is heated to soften during the extrusion or moulding process, prevention of hydrogen chloride elimination due to heat and subsequent decomposition is required. The stabiliser prevents such initial elimination of hydrogen chloride from PVC. Therefore, use of stabilisers is essential to prevent the chain reaction of decomposition. They can also make the PVC enhanced resistance to daylight, weathering and ageing and have an important influence on the physical properties and the cost of a formulation. They are invariably supplied in the form of application - specific blends of which the main constituents are metal soaps, metal salts and organometallic compounds. The choice of heat stabiliser depends on a number of factors including the technical requirements of the PVC product, regulatory approval requirements and cost. The main heat stabilisers in a formulation are usually combined with co-stabilisers which are organic materials such as polyols or epoxidised esters: they provide an additive synergistic effect, especially in the case of some forms of heat stabiliser, an enhancement of overall stabiliser performance. Every stabiliser has typical uses, although a number of different types may be used in the same application sector. Although lead-based systems are being voluntarily phased out within Europe under the Vinyl 2010 voluntary commitment of the PVC industry in favour of Ca/Zn or Ca/organic stabilisers, they still represent about one half by tonnage of the stabilisers used in Europe at present. They are mainly used for rigid PVC construction applications such as pipes/fittings and window profiles. The majority of tin - Sn - stabilisers are used for rigid wrapping films, roofing and transparent rigid sheets for construction applications. Tin stabilisers are employed for drinking waste applications in some countries where lead has been banned in this application for many years. The major metals contained in stabilisers are lead (Pb), barium (Ba), calcium (Ca), and tin (Sn). The stabilisers are classified into Pb stabilisers, Ba-Zn stabilisers, Ca-Zn stabilisers, and Sn stabilisers. Ba-Zn stabilisers and Ca-Zn stabilisers are used as metaillic soaps,such as stearates, while Sn stabilisers are used as organic tin (dialkyl tin compounds). Other than metallic soap, Pb stabilisers are used as basic sulphate, basic carbonate, or basic phosphate.

The difference and application of chlorinated polyethylene CPE135A and ACR401 CPE and ACR in the production of hard PVC (UPVC) most must be used, here we introduce the CPE and ACR respectively in the production of PVC application. CPE-135A is used as a low cost impact modifier for UPVC. ACR is used to promote plasticization in UPVC production. chlorinated polyethylene CPE135A: Firstly introduce Chlorinated Polyethylene CPE135A: CPE is the abbreviation of chlorinated polyethylene. It is the product of high-density polyethylene after chlorination, with the appearance of white fine particles.

Excellent stability. Usage of CPE135A chlorinated polyethyleneL CPE Chlorinated Polyethylene has the dual performance of plastic and rubber, and has good compatibility with other plastics and rubber, so in addition to a few used as the main material, CPE most and rubber or plastic. CPE-135A is mainly used as modifier when used with plastic. Its main purpose is to be an impact modifier of hard polyvinyl chloride (UPVC) products to improve the impact resistance and low temperature performance of UPVC. It can be used to manufacture UPVC doors and Windows profiles, pipes and injection products, etc. When used with rubber, CPE is mainly to improve the flame retardant, insulation, aging resistance and so on. In addition, CPE-130A is mostly used for rubber magnetic strip magnetic chip, etc. CPE-135C can be used as flame retardant ABS resin modifier, can also be used as injection PVC, PC, PE impact modifier. Second, let's introduce the PVC Processing Aid ACR: PVC processing assistant ACR is recognized as an ideal processing assistant for rigid PVC products, which can be added to any rigid PVC products according to the needs of different processing processes. Hengshui Homart Technology Co.,Ltd is a professional manufacturer of PVC additives, established in 1999, has 22 years of production experience and industry technical experience. The average molecular weight of PVC Processing Aid ACR401 is much higher than that of commonly used PVC resin, and its main function is to promote the melting of PVC resin, change the rheological property of melt body and improve the surface quality of products. Application: 1: pvc profile 2: pvc pipe 3: pipe fitting 4: pvc plate 5: pvc gusset, pvc panel, wpc panel, spc floor, etc. ACR530 is used for foaming PVC Board as Foaming Regulator. ACR functions: 1, better dispersion of PVC resin. 2, provide melt strength and uniformity. 3, effectively improve the surface finish of products. 4. Shorten the plasticizing time In the formulation of different products, the general dosage of ACR added is 1-2 kg ACR per 100 kg PVC resin. But for PVC Foaming Board dosage should be 8 - 10kg.

The Function of PVC Foaming Regulator (ACR530 PVC Foaming Regulator) in PVC Foaming Panel PVC Foaming regulator, is the methyl acrylic acid ester and acrylic ester raw materials via special copolymer prepared by emulsion polymerization process, can also be called ACR or Foaming regulator. For foaming adjusting-agent, viscosity is an important indicator, it represents the high and low molecular weight of foaming adjusting-agent, in order to adapt to the demand of PVC product market "calcium" (calcium powder added in large amount of foaming product), viscosity from the initial <10.0, to 10.0-11.0, until the present >=12.0. After market feedback Hengshui Homart Technology Co.,Ltd thick foaming board with foaming regulator viscosity even reached 13.0 above, stable performance, relatively small dosage. Downstream of the current situation, industry competition intensifies, many clients in order to improve the price competitive advantage, especially the foaming wood plastic products, often added in the foaming PVC formulations using a large number of small pipe material, plastic materials, such as secondary materials can greatly speed up the whole of the plasticizing plasticizing, so in order to obtain good foaming effect, we suggest appropriate lower the temperature in the cylinder 1, 2 area, Or use a slowly plasticizing melt strength of the foaming regulator. This can not only make the foaming effect better, but also save part of the foaming agent, PVC foaming products will be better quality. Of course, choosing the right manufacturer is also a priority. The detailed role of PVC foaming regulator is introduced below: 1. Characteristics of foaming regulator: In PVC foaming products, the purpose of adding ultra-high molecular weight polymer: one is to promote PVC plasticization; Two is in order to improve the melt strength of PVC foaming materials, prevent the merger of bubbles, in order to get uniform foaming products; Three is to ensure that the melt has good fluidity, in order to get good appearance of products. Since DIFFERENT FOAMING PRODUCTS manufacturers have different products, the equipment, technology, raw materials and lubrication system used are different, so we have developed foaming regulators with different properties to meet the different needs of users. 2. Classification of foaming sheet material According to the different foaming rate, can be divided into high foaming and low foaming, according to the soft and hard degree of bubble constitution, can be divided into hard, semi-hard, soft foam. According to the bubble structure can be divided into closed cell foam and open cell foam. Generally common PVC foam sheet material belongs to hard closed low foam sheet material. 3. The application of PVC foam sheet material PVC foam sheet material has the advantages of chemical corrosion resistance, weather resistance, flame retardant and so on. It is widely used in many aspects, including display panel, mark, billboard, partition, building board, furniture board and so on. 4. The key factors to evaluate the quality of foaming sheet For foamed material, the size and uniformity of the foam hole are the key factors affecting the quality of the sheet. For low foaming sheet material, the bubble hole is small and uniform, and the foaming sheet material has good toughness, high strength and good surface quality. From the aspect of reducing the density of foam sheet, only the small and uniform bubble hole can further reduce the possibility of density, and it is difficult to further reduce the density when the bubble is large and scattered. 5. Key points of PVC foaming process control Plastic foaming is divided into three processes: formation of bubble core, expansion of bubble core and solidification of bubble body. For PVC foam sheet with chemical foaming agent added, the expansion of bubble core has a decisive impact on the quality of foam sheet. PVC belongs to the straight chain molecule, the molecular chain is short, the melt strength is low, in the bubble core expansion into the bubble process, the melt is not enough to cover the bubble, the gas is easy to overflow and merge into a bubble, reduce the product quality of the foam sheet. The key factor to improve the quality of PVC foam sheet is to improve the melt strength of PVC. From the analysis of polymer material processing characteristics, there are many ways to improve the strength of PVC melt, but the most effective way is to add additives to improve the strength of the melt and reduce the processing temperature. PVC is an amorphous material, the melt strength decreases with the increase of melt temperature, on the contrary, the melt strength increases with the decrease of melt temperature, but the cooling effect is limited and only plays an auxiliary role. ACR processing agents have the effect of improving melt strength, and foaming regulator is the most effective. The melt strength increased with the increase of foaming regulator content. Generally speaking, as long as the screw has enough dispersive mixing ability, the effect of adding high viscosity foaming regulator to improve the melt strength is more obvious. 6 processing additives in PVC foam sheet material ACR processing additives can promote the melting of PVC, improve the surface finish, improve the elasticity of melt, and enhance the elongation and strength of melt. It is helpful to cover the bubble and prevent the collapse of the bubble hole. The molecular weight and dosage of foaming regulator have a great influence on the density of foaming sheet: with the increase of molecular weight, PVC melt strength, the density of foaming sheet can be lower, and improve the dosage of regulator has the same effect. However, this effect is not linear. Increasing the molecular weight or increasing the dosage will not significantly reduce the density, and the density will tend to be constant. Important relationship between foam regulator and foaming agent, the density of foamed sheet with foaming regulator is a balance point, in this balance, density of foamed sheet is not affected by the influence of foaming agent content, are held constant, is also increase dosage of foaming agent can't reduce the density, the cause of this phenomenon is under a certain amount of foam regulator dosage, The melt strength of PVC is limited, and excess gas causes bubble holes to collapse or merge. Choose the correct and most appropriate foaming regulator can be the best quality of foaming board, Hengshui Homart Technology Co., Ltd company's ACR530 PVC Foaming Regulator Processing Aid and CM - 90 PVC Processing Aid Foaming Regulator is suitable for foaming board and WPC board and other different products, our company in the PVC auxiliary industry has 22 years of production experience and accumulated rich technical experience, the service of many manufacturers of foaming board customers, stable quality and excellent

Analysis the reason why PVC Pipe Color change to Yellow and How to solve it. The main reason is that the dosage of stabilizer is not enough or grade is not good, should still have the phenomenon of redness. It's possible that a particularly bad stabilizer was used. Most of the cases are the problems brought by lubrication imbalance, too little lubrication, especially too little external sliding, over-plasticization caused by pipe discoloration, brittle, this situation Can add titanium dioxide, see if it can cover, if there is no try to add stabilizer or change, if it is calcium zinc stabilizer should pay more attention to the adjustment of sliding agent. In addition, lubricants affect plasticization, calcium carbonate is added whitening agent, and so on, there is PVC resin, other conditions are the same, with bad PVC will become more yellow, need more stabilizer. In general, will think of the problem of stabilizer, in fact, in the case of sufficient stability, lubrication is also a very important factor. In addition, if the calcium powder is damp, it will also affect the plasticization. The stabilizer is usually the first consideration, but the problem can generally be solved by adjusting the lubrication system properly. Eliminate the problem of stabilizer, then focus on sliding agent, dynamic balance. Stabilizers referred to in the industry generally do not contain antioxidants. But calcium zinc stabilizers generally contain antioxidants. The rutile type has a reddish background, while the anatase type has a bluish background. Rutile is better, but more expensive. Whether rutile type or anatase type titanium dioxide, in the visible wavelength range (400-700nm), their reflectance of light is very high, so they have a good whiteness. But in less than the visible light range such as 300-400 nm UV wavelength range, the performance of the two different crystal types of titanium dioxide is very different. For rutile titanium dioxide (red line) in the UV - A band with strong lethality (350-400nm) it is far lower than the blue titanium dioxide anatase, in other words, its UV absorption rate is significantly higher than the blue titanium dioxide anatase. In this case, it is around the film of organic resin to share the UV light is much less, so the service life of these organic matter is also long. This is why the rutile type of titanium self-powder, as we commonly call it, has much better weather resistance than the anatase type. These properties are innate. In extrusion is the type of titanium dioxide base color affects the color of the product, in the later use, titanium dioxide on ultraviolet absorption of different effects on the weatherability of the product to affect its color. Actually, rutile type titanium white just than sharp titanium type slightly yellow not turn yellow, the problem is stabilizer was more likely, it is possible that the use of the composite stabilizer, the current domestic some manufacturer of composite stabilizer added a large amount of lubricant to reduce cost, reduce the dosage of effective components, stability is slightly less than under the same weight. The temperature is too high, the compression ratio of the mold is too large, the amount of stabilizer is not enough, the lubrication system has problems, the stability of the resin itself is not enough, the calcium powder tide, the gap between the screw and the barrel has problems, the shear is too large, there are many reasons, but also according to the actual situation!
