PVC SG-8
PVC SG-8,
cable ducts raw material, PVC SG-8 used for the production of wall panels,
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.

Description:
Appearance PVC SG-8 is a homogeneous white powder, without taste and smell.
The use of PVC resin brand SG-8:
Resin brand SG-8 is used for the production of thin-walled profiled moldings, wall panels, cable ducts, semi-rigid products of General purpose (linoleum, artificial leather, plasticized films, three-dimensional polymer packaging).
Production method:
Obtained by polymerization of vinyl chloride. The polymerization is carried out in suspension (in water environment).
There are many methods of producing vinyl chloride from acetylene, ethylene dichloride, ethylene and ethane. Our products are based only on the use of ethylene.
