PA is a copolymer of methacrylate with acrylic ester. It is recognized that ACR is an ideal processing auxiliary of UPVC. According to the requirement of technological process, PA can be added to any formulation of UPVC. Our product is equivalent to the corresponding grade of American and Japanese companies.
The average molecular weight of processing aid ACR is by far higher than that of commonly-used PVC resin. It's mainly used to accelerate the melting of PVC resin, change the fluidity of the melting body and improve the surface quality of the products.
