PTFE tube is a fluoroplastic tube made of polytetrafluoroethylene material through mixing, pressing, cold extrusion, sintering and shaping.
PTFE is the earliest discovered fluoroplastic. Its English name is polytetrafluoroethylene tube. It is a high-quality plunger extrusion tube. It adopts special processing technology to make the steel pipe and plastic pipe tightly combined. It can withstand positive pressure of 1.6Mpa and negative pressure: 77Kpa; it can be used normally within -60℃～+260℃ and has reliable and excellent corrosion resistance.
PTFE has a very low friction coefficient and is a good anti-friction and self-lubricating material. Its static friction coefficient is smaller than the dynamic friction coefficient. Therefore, it is used to make bearings with small starting resistance and smooth operation. Because PTFE is non-polar, heat-resistant and non-absorbent, it is also an excellent electrical insulation material. It also has excellent aging resistance, non-stickiness and non-flammability.
It can transport highly corrosive gases and liquids at high temperatures, which cannot be replaced by other pipelines. The material has the characteristics of high temperature resistance, strong acid and alkali resistance, UV resistance, and weather resistance. PTFE tube is also called Teflon tube, Teflon tube, polytetrafluoroethylene tube, F4 tube, tetrafluoro tube, plastic king tube.
PTFE is water-resistant, physiologically inert and non-sticky, so it is used in many tissue repair materials and artificial organ materials, such as artificial blood vessels, heart repair membranes, etc. Moreover, the biggest advantage of PTFE is that it can be sterilized by any method, and it will not be denatured by high-pressure heating or various disinfectants. Therefore, it is widely used in medical devices such as sutures, disinfection pads, and injection needles.
Various special-shaped materials and parts such as rods, pipes, films, bearings, washers, valves, etc. made of polytetrafluoroethylene are widely used in machinery, chemical industry, aviation, electrical and electronic, national defense industry, cutting-edge technology, medical and health care, and electrical insulation.
