PVC development status bar

Everyone was very strange to hear PVC rods , PVC rods in fact, is a flame retardant , chemical stability , low rifting produced only internal forces of non- crystalline materials , is China's first , world's second largest general-purpose synthetic resin material, due to excellent flame resistance, abrasion resistance , chemical resistance , overall mechanical resistance, product transparency , electrical insulating properties , and easy processing characteristics, present , PVC has become the most widely applied in the field of plastic varieties First, in the industrial , construction, agriculture , daily life, packaging, power , utilities and other fields are widely used, and polyethylene (PE), polypropylene (PP), polystyrene (PS) and ABS collectively referred to as the five generic resin .
