PTFE material with its excellent corrosion resistance, corrosion-resistant materials has become a major petroleum, chemical, textile and other industries. Specific applications include: transporting corrosive gas pipes, exhaust pipes, steam pipes, rolling mill high pressure tubing, high voltage aircraft hydraulic systems and cold piping systems, distillation columns, heat exchangers, vessels, towers, tanks lining, valves and other chemical equipment. Performance is good or bad seal on the efficiency and performance of the entire equipment has a great impact. PTFE material with corrosion resistance, aging resistance, low coefficient of friction and is not sticky, wide temperature range and elastic properties make it very suitable for manufacturing high corrosion resistance requirements, the use of a temperature higher than 100 ℃ of seals. Such as machinery, heat exchangers, pressure vessels, large diameter vessels, valves, pumps slotted flange seals, glass 11:50, flat flanges, large diameter flange seals, shafts, piston rods, valve stem, Worm pump, rod seals and so on. Grade: PTFE or F-4 plate: thickness * width = 2 ~ 60mmx600mmx600mm; Bar: Diameter: 6 ~ 200mm.x 200mm / 1000mm * Features and Scope: high temperature resistance, corrosion resistance, excellent electrical insulation, resistance aging, water absorption, excellent self-lubricating properties. F-4 plastic commonly known as the king of almost all chemical corrosion-resistant (including aqua regia), but by the molten alkali metal erosion, low coefficient of friction, non-stick, non-absorbent, long-term use in -180 ~ 250 ℃. Low intensity, poor rigidity, large cold, not injection molding, sintering required. Used as a corrosion-resistant parts, less friction and wear parts, seals, high temperature insulation parts.
