Product Description
Polyvinyl chlorides is high molecular compounds polymerized with structural element as CH2-CHCLn,degree of polymerization usually as 590-1500.In the process of re-polymerization ,affected by kinds of factors such as the polymerization process, reaction conditions, reactant composition, additives etc.it can produce eight different types of PVC resin performance is different.
