Polyvinyl Chloride Resin (PVC Resin)

Capacity:400 Thousand MT/a

M. F. :[CH2-CHCI]n

M. W. :50000-100000(General purpose suspension resin)

Property:In normal ambient, PVC resin is amorphous white powder with density of 1.35-145g/cm3 and apparent density of 0.45-0.65g/cm3, not solved in water, gasoline, alcohol, but can solved in organic solvent such as ether, ketones, chloridized aliphatic hydrocarbons and aromatic hydrocarbons with many good functions such as antiflaming, high resistant on chemicals, high mechanical strengths and excellent electric insulativity.

Usage:PVC resin is widely used in plastic working. building material and light industry. It can be used as insulating layer of metal wire, thin sheet, board plates, hose, pipe, leathering, soft goods and toy, as well as food or drug packaging film or packaging box.

Quality Standard:GB/T 5761-2006
