Polyvinyl Chloride resin (PVC RESIN)
Basic Information
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.
