Description
Polyvinyl chloride is high molecular compounds polymerized by vinyl
chloride monomer (VCM) with structural element as
[CH2-CHCL]n,degree of polymerization usually as 590-1500.According
to residual content of vinyl chloride menomerl in polyvinyl
chloride resin , is can be divided into:commercial grade, food
hygiene grade and medical application grade.In appearance,
polyvinyl chloride resin is white powder.
Applications:
1. PVC resin SG3 is used for soft material, pvc sheet, pvc film,
leather,tubes, table cloth, tape.
2. PVC resin SG5 is general type.
Mainly used for pipe and windows structural section.
Also it can be used for electric insulation material, tubes,
artificial leather.
