Poly(tetrafluoroethylene) CAS NO.9002-84-0

1, the application of corrosion resistance due to rubber, glass, metal alloys and other materials in corrosion resistance defects, it is difficult to meet the harsh conditions of temperature, pressure and chemical media coexistence of the environment, the resulting loss is quite amazing. PTFE material with its excellent corrosion resistance, has become the petroleum, chemical, textile and other industries of the main corrosion resistance material. Its specific applications include: conveying corrosive gas conveying pipe, exhaust pipe, steam pipe, rolling mill high pressure pipe, aircraft hydraulic system and cold pressure system of high and low pressure pipe, distillation tower, heat exchanger, tank, tank lining, valves and other chemical equipment. The performance of seals has a great impact on the efficiency and performance of the entire machine equipment. PTFE material has corrosion resistance, aging resistance, low friction coefficient and non-viscosity, wide temperature range, good elasticity characteristics make it very suitable for the manufacture of high corrosion resistance requirements, the use of temperature above 100℃ seals. Such as machines, heat exchangers, high pressure vessels, large diameter containers, valves, pump groove flange seals, glass reaction pot, plane flange, large diameter flange seals, shaft, piston rod, valve rod, worm wheel pump, pull rod seals and so on. 2, the application of low friction performance in load due to the friction part of some equipment should not be lubricated, such as in the lubricating oil will be dissolved by solvents and failure occasions or papermaking, pharmaceutical, food, textile and other industrial products need to avoid lubricating oil contamination, This makes PTFE filled materials the ideal material for oil-free lubrication of mechanical equipment parts (directly under load). This is because the material has the lowest friction coefficient of any known solid material. Its specific uses include bearings for chemical equipment, paper making machinery, agricultural machinery, as piston rings, machine tool guide rails, guide rings; In civil engineering, it is widely used as the support slider of bridge, tunnel, steel structure roof truss, large chemical pipeline, storage tank, and used as bridge support and bridge rotation.
