1. PVC Resin
>Property
The thermoplastic high-molecular polymer made by the suspension polymerization of vinyl chloride monomer. The molecular formula :- (CH2 - CHCl) n - (N: degree of polymerization, N= 590 ~ 1500). It is the most widely raw material used in plastic production. It has good chemical stability, corrosion resistance and water resistance.
>Type
SG3, SG5, SG7, SG8
>Application
Polyvinyl chloride resin has a wide range of applications, such as automobile interiors, family decorative materials, advertising light box, shoe soles, PVC pipes and fittings, PVC profiles and hose, PVC sheet and plate, rolling film, inflatable toys, outdoor products, PVC wire and cable, PVC artificial leather, wood and plastic floor, corrugated board, etc.
