Polytetrafluoroethylene (PTFE) is the heaviest of the plastics. With a wide range of temperature range (-250~260), good chemical stability, excellent dielectric properties, self lubrication and anti stickiness, it has a wide range of applications.
It can be used as anticorrosive material in chemical industry, and can manufacture various anti-corrosion parts, such as pipes, valves, pumps and fittings fittings. For chemical equipment, lining and coating of reactor, distillation tower and anticorrosive equipment can be made.
For mechanical purposes, it can be used as self-lubricating bearings, piston rings, oil seals and sealing rings. Self lubrication can reduce wear and heat and reduce power consumption.
In terms of electrical and electronic equipment, it is mainly used to manufacture various kinds of wires and cables, battery electrodes, battery separator, printed circuit boards, etc.
In medical materials, it can be used as materials for various medical devices and artificial organs by using its heat resistance, water resistance and non-toxic properties. The former is like sterilizing filter, beaker, artificial heart lung device, such as artificial blood vessel, heart and esophagus.
