PTFE has some unique properties, which make it widely used in some industries, such as chemical industry, silicon sheet, oil, textile, food, paper making, medicine, electrical, mechanical and offshore operation. Is often used in the manufacture of ptfe rods, teflon slice and PTFE Film Tape. 1, the application of anti-corrosion propertySome hose, glass and metal alloy material, such as corrosion resistance, is not so good, so they cannot be used in the environment, the requirement with high temperature, pressure and chemical medium. Now, PTFE as its superior corrosion resistance, in petroleum, chemical, textile, the main material of use. It is mainly used to make delivery corrosive air, exhaust pipe, steam pipe, high pressure oil pipe in the rolling mill hydraulic system, high, medium and low pressure pipe and cold system used to transfer pipe plane, rectifying tower, heat exchanger, the reaction kettle, in the tower groove lining and valve, etc. However, the performance of the sealing material is good or bad performance and efficiency, will have great influence on the whole machine. PTFE has good corrosion resistance, aging resistance, low friction coefficient, viscosity properties, wide temperature range and under elastic, so it is suitable to be used to make use of in the environment of the sealing material, and the temperature of one hundred degrees Celsius and seal material requirements high corrosion resistance, such as in the machine, the seal material heat exchanger, high pressure vessel, and large diameter containers, valve, groove of the flange of the pump, plastic reaction pot, surface flange, and large diameter of the flange, the shaft, piston rod, stem, turbine pump and rod, and electronic and electric fieldPTFE of the application is low loss and small dielectric constant, so it can use, make PTFE sheet, was applied in the mini engine, thermocouple and control equipment. Teflon film capacitor, used in the wireless equipment insulation support, cable, motor and transformer ideal material. This is also a lot of use, make the electronic components in the aviation and aerospace fields is one of the indispensable materials. Because the oxygen can penetrate through the PTFE teflon film easy, and steam can infiltration PTFE teflon film difficult, with this property, we invented the oxygen sensor. When PTFE is high temperature and high pressure environment, will deviate from polarization charge. According to the properties, we can use it to make the microphone, speaker and robots. We can also use it to make optical fiber with its low refractive index.
