- Oct 20, 2019-

PVC material is polyvinyl chloride, which is one of the largest plastic products in the world. It is cheap and widely used. The polyvinyl chloride resin is white or light yellow powder. It cannot be used alone and must be modified. PVC is a white powder with an amorphous structure, which has a small degree of branching and poor stability to light and heat. Different additives can be added according to different purposes, and polyvinyl chloride plastic can exhibit different physical properties and mechanical properties. A variety of hard, soft and transparent articles can be made by adding an appropriate amount of plasticizer to the polyvinyl chloride resin.

Main use of PVC

Due to its high chemical stability, it can be used to make anti-corrosion pipes, pipe fittings, oil pipelines, centrifugal pumps and blowers. The hard board of polyvinyl chloride is widely used in the chemical industry to make linings for various storage tanks, corrugated boards of buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used in the electrical and electronic industries to manufacture plugs, sockets, switches and cables, acid and alkali resistant hoses, cable sheaths, insulation layers, etc. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather!
