PTFE Tube Corrosion resistant materials

The unique performance of Teflon has a wide range of applications in the fields of chemical, petroleum, textile, food, paper, medical, electronic and mechanical industries and marine operations.

1, the application of anti-corrosion properties

As the rubber, glass, metal alloys and other materials in the corrosion-resistant defects, it is difficult to meet the harsh conditions of temperature, pressure and chemical medium coexistence of the environment, the resulting loss is quite amazing. The ptfe material with its excellent corrosion resistance, has become the oil, chemical, textile and other industries the main corrosion-resistant materials. The specific applications include: conveying corrosive gas transmission pipe, exhaust pipe, steam pipe, rolling mill high pressure tubing, aircraft hydraulic system and cold pressure system of high and low pressure pipes, distillation tower, heat exchanger, kettle, tower, tank Of the lining, valves and other chemical equipment.

Seal the performance of the entire machine equipment efficiency and performance have a great impact. ptfe material with corrosion resistance, aging resistance, low coefficient of friction and non-sticky, wide temperature range, good elastic properties make it very suitable for use in the manufacture of high corrosion resistance requirements, the use of temperature higher than 100 ℃ seal. Such as machines, heat exchangers, high pressure vessels, large diameter containers, valves, pump groove seal, glass reaction pot, flat flange, large diameter flange seal, shaft, piston rod, Worm gear, rod seals and so on.

2, low friction performance in the application of the load

Because some of the friction parts of the equipment should not be lubricated, for example, in the case where the lubricating grease is dissolved by the solvent or the products in the industrial areas such as papermaking, pharmaceutical, food, textile and the like need to avoid contamination of the lubricating oil, the ptfe material Mechanical equipment parts of the oil-free lubrication (direct load) the best material. This is because the friction coefficient of the material is the lowest of known solid materials. Its specific uses include for the chemical equipment, paper machinery, agricultural machinery bearings, used as a piston ring, machine tool guide, guide ring; in civil engineering works widely used as bridges, tunnels, steel roof trusses, large chemical pipes, Support sliders, as well as bridge bearings and bridge dike and so on.

3, in the electrical and electronic applications

The ptfe film is ideal for manufacturing capacitors, Insulation materials, but also aerospace and other industrial electronic components indispensable one of the materials; the use of fluorine plastic film on the oxygen permeability, and the permeability of water vapor permeability of this choice of permeability, can produce oxygen sensor; The use of fluorine plastic at high temperature, high pressure under the phenomenon of extreme charge deviation phenomenon, can produce microphones, speakers, robots on the parts; the use of its low refractive index characteristics, can produce optical fiber.
