PTFE extruded rod is a corrosion-resistant product, so it is generally suitable for various products working in corrosive media.
The bar produced from this raw material has many excellent characteristics, and the temperature range is very wide, from -200 ° C to + 260 ° C. Very low water absorption, and has a series of unique properties such as self-lubricity and non-stickiness. Excellent mechanical properties include aging resistance especially for bending and swing applications. Corrosion resistance to basically all chemicals except some fluorides and alkaline metal liquids. Outstanding flame retardance, in accordance with ASTM-D635 and D470 test procedures, and is regulated as a flame retardant material in air. Excellent insulation properties, regardless of frequency and temperature.
At present, there are two production methods, there are two types of push rods and molded rods. Among known plastics, polytetrafluoroethylene has the best chemical resistance and dielectric properties. It can be used at temperatures of -180 ℃-+ 260 ℃. Use, and have the lowest coefficient of friction, mainly suitable for some long products and non-standard specifications of mechanical parts: seals / gaskets, ring materials, wear plates / seat block, insulation parts, corrosion resistance industry, mechanical parts, lining , Oil and gas, petrochemical industry, chemical industry, equipment manufacturers, etc.
Due to its excellent performance, its application fields are also very wide:
Electronic appliances: mainly used in the manufacture of various wires and cables, battery electrodes, battery separators, printed circuit boards, etc.
Chemical industry: Can be used as anti-corrosion material, can manufacture various anti-corrosion parts, such as pipes, valves, pumps and pipe fittings. In the field of chemical equipment, linings and coatings for reactors, distillation towers and anticorrosive equipment can be made.
Medical materials: Utilizing its heat-resistant, water-resistant and non-toxic properties, it can be used as a material for various medical devices and artificial organs. The former are sterilizing filters, beakers, artificial heart and lung devices, and the latter are artificial blood vessels, heart and esophagus. It has been widely used as a sealing material and a filling material.
Mechanical aspects: can be used as self-lubricating bearings, piston rings, oil seals and seals. Self-lubricating can reduce the wear and heat of machine parts, and reduce power consumption.
You can see its many outstanding performances are fully utilized.
