Virgin Medical Grade PVC Resin K70 Micro Fine 1-2 Um Diameter Eco Friendly
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.
