ACR resin is a new and rapidly developing modifier for polyvinyl chloride, which has excellent weather resistance, extremely high impact modification effect, and good processing flowability. It is usually prepared by lotion polymerization or suspension polymerization of methyl methacrylate, a small amount of acrylate (such as butyl acrylate, ethyl acrylate) and styrene. These characteristics make ACR resin perform well in PVC processing, significantly improving the plasticization rate and melt rheological properties of PVC.

The role of ACR resin in PVC processing mainly includes improving the plasticization process of PVC, enhancing the rheological properties of PVC melt, and improving the surface quality of PVC.

ACR resin, as a processing aid for PVC, can significantly improve the plasticization rate of PVC, reduce plasticization time, and does not affect the final physical properties of the material.

In addition, ACR resin also has good processing fluidity and color stability, which is suitable for improving the processing and impact resistance of PVC. ‌
