PTFE's unique properties make it have a wide range of applications in the field of chemical, petroleum, textile, food, paper, medicine, electronics, and machinery and other industrial and marine operations.

1, the application of anti-corrosion

Rubber, glass, metal alloys and other materials in the corrosion resistance there is a defect, it is difficult to meet the environment of the harsh conditions of temperature, pressure and chemical medium coexist, the resulting loss is quite staggering. PTFE material with its excellent corrosion resistance has become a major petroleum, chemical, textile and other industries corrosion-resistant materials. Specific applications include: high school low pressure pipeline pipeline conveying corrosive gas, exhaust pipes, steam pipes, rolling mill, high pressure tubing, aircraft hydraulic system and cold system, distillation columns, heat exchanger, kettle, tower, trough lining, valves, chemical equipment.

The seal performance good or bad has a great impact on the efficiency and performance of the entire machinery and equipment.PTFE material with corrosion-resistant, anti-aging, low friction coefficient and not sticky, wide temperature range, good flexibility makes it very suitable for the manufacture of corrosion resistant requirements of high use temperature higher than 100 ° C seals.Such machines, heat exchangers, pressure vessels, large diameter containers, valves, pumps, a grooved flange seal glass Fanyingguo, a flange, the seal member of the large diameter flange, the shaft, the piston rod, the valve rod, The worm pump, rod seals.
