One.
Ptfe Plate high temperature resistance
1, PTFE commonly known as plastic king, is a kind of tetrafluoroethylene as a monomer polymerization of polymer. White, translucent, excellent heat and cold resistance, can be used at -180 ~ 260ºC for a long time. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, almost insoluble in all solvents. At the same time PTFE has the characteristics of high temperature resistance, its friction coefficient is low.
2, PTFE plate long-term high temperature resistance of 260 degrees, instant high temperature resistance of 300 degrees. Ptfe is a kind of fluorine plastics, can work in the environment of minus 180 degrees to 260 degrees, with corrosion resistance, wear resistance, high pressure resistance, aging resistance and Other characteristics, widely used in national defense, electronics, pesticides, medicine, machinery, chemical industry and other fields.
Two, the difference between silicone gasket and polytetrafluoroethylene gasket
1. Different characteristics
(1) Silicone gasket has a certain tension, flexibility, excellent insulation, pressure resistance, high temperature resistance, chemical stability, environmental protection and safety, no odor, is a kind of green products with high activity.
(2) polytetrafluoroethylene gasket has the characteristics of acid and alkali resistance, high temperature resistance and resistance to various organic solvents.
2. Different uses
(1) Silicone gasket is widely used in plexiglass, glass crafts, display shelves, household appliances, hardware accessories, transparent plastic products, etc.
(2) PTFE gaskets are widely used in petroleum, chemical, pharmaceutical, electric power, iron and steel industries.
3. Different functions
(1) Silicone gasket with shockproof, anti-slip, anti-collision, anti-scratch functions, high transparency.
(2) polytetrafluoroethylene gasket has good mechanical toughness, strong acid and alkali resistance.(YNMT)·
