High reputation PVC Resin SG7 - Polyvinyl chloride pipe grade – Junhai
High reputation PVC Resin SG7 - Polyvinyl chloride pipe grade – Junhai Detail:
Polyvinyl Chloride (PVC) is a linear thermoplastic resin produced by polymerization of vinyl chloride monomer. Due to the differenceof raw materials, there are two methods of synthesizing vinyl chloride monomer calcium carbide process and petroleum process. Sinopec PVC adopts two suspension process, respectively from Japanese Shin-Etsu Chemical Company and American Oxy Vinyls Company. The product has good chemical corrosion resistance, excellent electrical insulation property and fine chemical stability. With high chlorine content, the material has good fire retardance and self-extinguishing properties. PVC is easy to process by extrusion, injection molding, calendering, blow molding, compressing, cast moulding and thermal molding, etc.
Application
PVC is one of the most widely used thermoplastic resins. It can be used to make products with high hardness and strength, such as pipes and fittings, profiled doors, windows and packaging sheets.
It can also make soft products, such as films, sheets, electrical wires and cables, floorboards and synthetic leather, by addition of plasticizers.
Pvc resin pipe grade is widely used in drainage pipe,irrigation pipes,bellows,sewer pipes, threading pipe production.
