Polyvinyl chloride has the outstanding characteristics of abundant raw materials (oil, limestone, coke, salt and natural ),mature manufacturing process, low price, and wide range of uses. It has become the second largest general-purpose resin in the world after polyethylene resin. 29% of the world's total synthetic resin consumption. Polyvinyl chloride is easy to process and can be processed by molding, laminating, injection molding, extrusion, calendering, blow molding, etc. Polyvinyl chloride is mainly used to produce soft plastic products such as artificial leather, films, and wire sheaths, as well as hard plastic products such as plates, doors and windows, pipes and valves.
