Product Description

PVC is high molecular compounds polymerized by VCM 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. PVC resin is white powder or pellet.

Property
Most widely raw material used in plastic production. It has good chemical stability corrosion resistance and water resistance. It can be dissolved in hydrochloric ether, ester and some alcohol . It can offer good solubility,good electrical insulation , thermoplasticity and membrane forming capacity.
The PVC Resins are polymerized by suspension process, their appearance being in white powder form. They are essential materials for preparing PVC compounds. By adding blending agents and employing different techniques,they can be made into rigid or non rigid PVC products and are suppliable in a wide range of transparent, translucent,and opaque colours
