PVC Impact Modifier Acrylic Impact Modifier ACR-LS Series

Core - Shell Structure: It uses cross - linked butyl acrylate as the core, and the outer layer is graft - copolymerized with methyl methacrylate. This structure enables it to improve the impact strength of PVC while having good compatibility with PVC.
Excellent Impact Performance: It can significantly improve the impact strength of PVC products at room temperature and low temperature. For example, LS - 55 has outstanding impact performance at room temperature and low temperature, which can meet the requirements of different use environments.
Good Processability: It can shorten the melting and plasticizing time of PVC, improve the processing ability, broaden the processing range, and has unique processing aid functions. In some formulations, there is no need to add additional processing aids when using it.
Other Advantages: It has good weather resistance. After long - term weather resistance tests, it can maintain impact performance and color stability. It can also ensure the dimensional stability of products and improve the surface finish and gloss of products.
