AS-869 is a styrene-acrylonitrile copolymer with ultra-high molecular weight which amounts to 5,000,000. Compared to other processing aid, it has advantages of smaller additions with similar processing function and lower cost.
AS-869 offers the following benefits：
- Good dispersion into PVC and other polymer.
- Decrease the fusion time, improve foam cell structure and strength.
- Improve thermoforming control.
- Facilitate high gloss for ABS and other polymer.
