Take you to know the "plastic king" in industry

                         ——Polytetrafluoroethylene


Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), commonly known as "plastic king", is a polymer obtained by polymerizing tetrafluoroethylene as a monomer. White waxy, translucent, excellent heat resistance and cold resistance, can be used for a long time at -180~260ºC. This material has the characteristics of acid resistance, alkali resistance, and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is extremely low, so it can be used for lubrication, and it has become an ideal coating for easy cleaning of the inner layer of the water pipe

White, odorless, tasteless, non-toxic powder, commonly known as "plastic king". Has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good aging resistance. High temperature resistance, working temperature up to 250℃. Low temperature resistance, good mechanical toughness at low temperature, even if the temperature drops to -196 ℃, it can maintain 5% elongation. Corrosion resistance, inert to most chemicals and solvents, resistant to strong acids and bases, water and various organic solvents. It has good weather resistance and the best aging life in plastics, which is why it is very popular in the industrial field.

1. Application: Used in electrical industry, used as insulation layer of power supply and signal line in aerospace, aviation, electronics, instrument, computer and other industries. Corrosion-resistant and wear-resistant materials can be used to make films, tube sheets, bearings, gaskets, valves And chemical pipelines, pipe fittings, equipment container lining, etc. 

2. It is used in electrical appliances, chemical industry, aviation, machinery and other fields to replace quartz glassware. It is used in ultra-pure chemical analysis and storage of various industries such as atomic energy, medicine, and semiconductors. It can be made into highly insulating electrical parts. It can be used as additives for plastics, rubbers, paints, inks, lubricants, greases, etc., high-frequency wire and cable sheathing, corrosion-resistant chemical vessels, high-temperature resistant oil pipelines, artificial organs, etc.

3. KALSHINE innovatively added other additives on the basis of polytetrafluoroethylene in the extrusion traction belt of the XPS extruded board production line, which greatly improved the smoothness of the surface and greatly reduced the generation of static electricity. It retains the characteristics of high temperature resistance, corrosion resistance and long service life. It can minimize the risk of fire during the foaming process of flammable and explosive gases, greatly reducing production costs and ensuring the stability of production and sustainability.
