Property:
Polyvinyl chloride is high molecular compounds polymerized by monomer with structural element as CH2-CHCLn,degree of polymerization usually as 590-1500.In the process of re-polymerization ,affected by kinds of factors such as the polymerization process, reaction conditions, reactant composition, additives etc.it can produce eight different types of PVC resin performance is different. According to residual content 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 or pellet.
Application:
Polyvinyl chloride resin is widely used in production of polyvinyl chloride boardy leatheroid, paint and adhesive agents,tec. Paint and adhesive .Division according to application: 1.Building materials: such as UPVC tubing, UPVC pipes, panel and section bars. 2.Packing materials. 3.Electronic materials: such as electronic wires, cables,adhesive tapes and bolts. 4.Furniture and decorating materials,etc. 5.Others: leatheroid, medical disposable products, antiseptic paint,etc.
