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.
Performance of CPE:
1, excellent aging resistance, can be used in harsh climate and harsh environment, has sufficient resistance to ozone.
2, excellent flammability, no spontaneous combustion.
3, excellent low temperature toughness, can maintain flexibility at -20℃, suitable for UPVC products impact modifier.
4, excellent resistance to chemicals, inert to most chemicals, corrosion resistance to various acids and bases.
5, good processing performance, easy to process molding.
6, excellent use safety, will not have a bad impact on the human body and the surrounding environment.
7. 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.
