For Rigid PVC Plastic product must input Processing Aid ACR in the formula in order to enhance the final product property, but do you know why must add ACR in formula and what is the function of Processing Aid ACR ?
PVC Processing Aid ACR is a kind of polymer copolymer of acrylates. It is a kind of white powder which is easy to flow. It is non-toxic and non-corrosive, the true density is 1.05-1.20 g/cm.
The Processing Aid ACR produced by JIUZ GROUP is a kind of excellent impact modifier for PVC, the utility model can effectively improve the toughness of the plastics and the impact resistance and the surface gloss of the products. ACR is a plastic additive with both impact resistance and processing modification functions, the PVC products have excellent impact resistance, low temperature toughness, compatibility with PVC, weatherability, stability, processability, and moderate performance and price ratio, can obviously improve the fluidity of PVC melt, thermal deformation, promote plasticizing, product surface smooth and beautiful, the characteristics are as follows:
1) accelerating the plasticizing process of PVC can obviously shorten the plasticizing time, speed up the melting, and promote the plasticizing.
2) improving the rheological properties of thermoplastic melt, effectively promoting the fluidity of PVC mixture, making the thickness of products more uniform.
3) improve the mechanical properties of the melt, eliminate the formation of bubbles, improve the elongation of the melt and overcome the problem of melt rupture.
4) improve the surface quality of products. From the appearance of products, ACR can significantly improve the surface gloss of products, make products look smooth and delicate.
PVC Processing Aid ACR is mainly used in hard and semi-hard polyvinyl chloride products, especially in plastic building materials, such as pvc window profile, pvc pipes, pipefitting, sheets, foaming board, etc. In summary, although the dosage of processing aid ACR is very small, but it plays a very important role in improving the processing properties of PVC Resin.
