Pvc 67

Polymers PVC suspension resin: S6721

Polymers PVC S6721 is a free flowing white powder produced by a suspension polymerisation process that ensures
high purity and consistent quality. Its consistent apparent density, excellent heat stability and ideal molecular mass
provide the optimal blend of high output and consistent gelation in rigid PVC extrusion, while its good plasticizer
absorption makes it suitable for flexible and semi-rigid PVC applications.
