PVC processing aid--New product

PVC processing aid--New product

Pure PVC resin is easy to decompose, has poor fluidity, low impact strength and poor weather resistance during processing, so various auxiliary materials need to be added during processing to improve its performance. Such as: lubricants, heat stabilizers, impact modifiers, processing aids, etc.

Depending on the usage, PVC processing aids are divided into many types. We can customize it as customer’s application.

BR-40 is a medium molecular weight all-acrylic copolymer processing aid for PVC applications including high output extrusion，injection, and high quality rigid PVC products. . It efficiently improves the melt elasticity, melt strength and sizing of rigid PVC through the use of BR-40
