Classification and advantages of PVC
PVC曾是世界上产量最大的通用塑料，是五大通用塑料之一（PE聚乙烯、PP聚丙烯、PVC聚氯乙烯、PS聚苯乙烯、ABS）。应用非常广泛。在建筑材料、工业制品、日用品、地板革、地板砖、人造革、管材、电线电缆、包装膜、瓶、发泡材料、密封材料、纤维等方面均有广泛应用。
Polyvinyl chloride , short for PVC. rank first in it’s production worldwide. It is one kind of common raw material making plastic. (PE-polyethylene, PP-polypropylene, PVC, PS-polystyrene, ABS)
It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
Classification of PVC
根据应用范围的不同，PVC可分为：通用型PVC树脂、高聚合度PVC树脂、交联PVC树脂。根据聚合方法，聚氯乙烯可分为四大类：悬浮法聚氯乙烯、乳液法聚氯乙烯、本体法聚氯乙烯、溶液法聚氯乙烯。
According to the different scope of application, PVC can be divided into general PVC resin, high degree of polymerization PVC resin and cross-linked PVC resin. According to polymerization methods, PVC can be divided into four categories: suspension PVC, lotion PVC, bulk PVC and solution PVC.
Advantages of PVC
聚氯乙烯具有阻燃（阻燃值为40以上）、耐化学药品性高（耐浓盐酸、浓度为90%的硫酸、浓度为60%的硝酸和浓度20%的氢氧化钠）、机械强度及电绝缘性良好的优点。
PVC has the advantages of flame retardant (flame retardant value is above 40), high chemical resistance (resistance to concentrated hydrochloric acid, sulfuric acid with concentration of 90%, nitric acid with concentration of 60% and sodium hydroxide with concentration of 20%), good mechanical strength and electrical insulation.
