Polyvinyl Chloride (PVC)
PVC fragments are flakes, from stationery packaging film, made out of broken pipes and other debris places.
Description:
PVC is usually expressed as the number sticky polymer molecular size, divided polymer models. In the international arena as well as with the K value or degree of polymerization of the polymer model to divide.
PVC resin is a non-crystalline linear polymer compound, and the relative molecular mass greater the viscosity, the higher the strength, stiffness, toughness, heat resistance and low-temperature resistance as possible, but the molding processability is worse.
Applications:
Widely used in pvc pipes, window profiles, films, sheets, tubes, shoes, fittings, etc.
