Pipe Grade PVC Resin SG5 Polyvinyl Chloride Resin For Calcium Carbonate Mix
PVC Resin
Polyvinyl chloride has the outstanding characteristics of abundant raw materials (oil, limestone, coke, salt and natural gas),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.
Polyvinyl chloride is flame-retardant (flame retardant value above 40), high chemical resistance (resistant to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), mechanical strength And the advantages of good electrical insulation. But its heat resistance is poor, with a softening point of 80¡ãC, it starts to decompose and change color at 130¡ãC, and precipitate HCI.
