  • INQUIRY

HR-20, HR-551 is a processing aid based on a low molecular weight acrylic polymer resin. HR-20 can be used in rigid PVC formulations to improve process ability and the surface quality.
1) Accelerated fusion rate, increase productivity and decreased processing temperature.
2) Better dispersion of additives into PVC, more homogenous melt of PVC, etc.
3) Excellent clarity and surface quality for end-use products, superior fusion promotion for rigid and soft PVC. Increased output rates and improved production efficiency.
Foam products: Sheets, WPC Profiles, pipes , films
