PVC resin

Polyvinyl Chloride (PVC) is a linear thermoplastic resin produced by polymerization of vinyl chloride monomer. Due to the difference of raw materials, there are two methods of synthesizing vinyl chloride monomer - calcium carbide process and petroleum process. 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 elec trical 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.

 

Package, Storage and Transportation

 

The resin is packaged in compound bags of kraft paper and coated PP woven material, or internally coated PP woven cloth exterior bags with LDPE interior bags, or packaged in bulk. The net weight of small package is *5Kg per bag and that of large package is ***0Kg, ***0Kg, **0Kg or **0Kg per bag. The resin should be stored in well-ventilated and dry warehouses against fire, sunlight and dampness, and should not be piled up in the open air. Clean and covered transportation vehicles should be used for transportation to prevent from rain.

 

 

   

Applications

 

PVC is one of the most widely used thermoplastic resins.It can be used to make products with high hardness andstrength, such as pipes and fittings, profiled doors, windows and packaging sheets. It can also make soft products, suchas films, sheets, electrical wires and cables, floorboards andsynthetic leather, by addition of plasticizers.
