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 application grade.In appearance, polyvinyl chloride resin is white powder. The product meets GB/T 5761-2006 standard with its physical and chemical properties meeting requirement in table below: 1.The user can choose any one from vifscosity number, K value ,index of average polymerizapion degree. 2.The user can confer with the manufacture if they have other index ,requirement ,on thermal stability.Molecular Formular :(CH2-CHCL)n
