PTFE Pushed Pure Rod

PTFE rods are available in push rods and molded rods. In known plastics, PTFE has the best chemical and dielectric properties and can be used at temperatures from -180 ° C to +260 ° C. And with the lowest coefficient of friction, mainly for some long products and non-standard mechanical parts: seals / gaskets, rings, wear plates / seats, insulation parts, corrosion resistance industry, mechanical parts, lining, Oil and gas, petrochemical industry, chemical industry, instruments and equipment....

Product Description

PTFE (Teflon) is the mostly consumed category of florin plastics, Which has the lowest coefficient of friction in all the engineering plastics,but its properties remain at a useful level over a great temperature range — from -400 to 500°F (-240 to 260°C).

PTFE Teflon material has the following main characteristics: the excellent chemical corrosion-resistance, which is able to endure All kind of chemistry material. And it has rather good electricity-resistance, which is not affected by the temperature and is called“ Kind of plastics”. PTFE plastic has excellent corrosion-resistance, aging-resistance, high(low) temperature resistance, good lubrication and insulation, non-adhesiveness, toxicological harmless. It is widely used in industries like aviation, chemical industry, electric and electronics, bridge, mechanical manufacturing, textile, paper making, ceramics etc.
