Application:
1. anti-corrosion
In chemical anticorrosion equipment, pipeline, mechanical manufacturing all kinds of anti corrosion of parts, such as pipe, valves, diaphragm, expansion joints of pump. Porous PTFE can also as strong corrosive medium of filtration material. Due to the PTFE does not stain reaction medium, therefore, PTFE manufacturing reactor, distillation tower is used to refine the requirements of ultra pure substance is a good material, but also can be used for chemical equipment corrosion linings and coatings.
2. lubrication, sealing
With PTFE manufacturing all kinds of packing belt, gaskets, seals, valve seat ring, etc., with various filler PTFE products used in bearing various requirements of self-lubricating and wear-resisting, piston ring and so on. For example, using graphite PTFE guide ring filler, used in non oil lubricated compressor; PTFE piston ring plus quartz sand used in oxygen compressor; oil-free piston ring filled with graphite and MoS2, liquefaction device used in helium, the low temperature of -269℃ use efficiency is good; with MoS2, silica, copper powder as a filler PTFE piston ring, the air compressor operating temperature of 150℃ to run on the piers can be good; the bridge deck due to thermal expansion and contraction with the retractable PTFE slider.
3. electrical insulation
PTFE as an electrical insulating materials are widely used in the requirements of good high frequency characteristics and highly resistant to heat, cold resistance, water resistance, resistance to corrosion, aging etc. the occasions. For example, used in a wide range of temperature change fierce jet aircraft, radar and other such as the insulation of the high frequency electronic instrument, high frequency cable, flexible cable, motor groove, capacitor insulation and printed circuit board.
4. non-stick
Because of PTFE and other material is not sticky, in plastics processing, food processing and other industries widely stripping agent, cookware coated with PTFE can be no cooking oil, plastic film heat welding commonly used PTFE glass cloth as viscous spacer and so on.
