Due to the defects in corrosion resistance of materials such as rubber, glass, and metal alloys, it is difficult to meet the harsh environment of coexistence of temperature, pressure and chemical medium, and the resulting losses are quite alarming. The PTFE material has its excellent corrosion resistance and has become the main corrosion-resistant material in the chemical industry. Its specific applications include: conveying pipes for corrosive gases, exhaust pipes, steam pipes, high, medium and low pipes of cold pressing systems, valves and other chemical equipment.
The performance of the seal has a great influence on the efficiency and performance of the entire machine and equipment. PTFE material has the characteristics of corrosion resistance, aging resistance, low friction coefficient, non-stickiness, wide temperature resistance range and good elasticity, making it very suitable for manufacturing seals with high corrosion resistance requirements and operating temperature higher than 100 °C. Such as machines, high pressure vessels, valves, seals of grooved flanges of pumps, valve stems, seals of tie rods, etc.
