PTFE Molding Powder 4s01-B
Good chemical stability, excellent dielectric performance, self-lubricating and anti stickiness. Therefore, its application range is expanding year by year. And a wide range of high and low temperature applications, it can be used as anti-corrosion material in chemical industry and can be used to manufacture various anti-corrosion parts, such as pipes, valves, pumps and pipe fittings.
Product Description:
Polytetrafluoroethylene resin is an important fluorine-containing plastic. It has a series of unique properties such as wide temperature range, good chemical stability, excellent dielectric performance, self-lubricating and anti stickiness.
In terms of chemical equipment, it can make liners and coatings for reactors, distillation towers and anti-corrosion equipment; In the mechanical aspect, it can be used as self-lubricating bearings, piston rings, oil seals and sealing rings. Self lubrication can reduce wear and heat of parts and reduce power consumption; In the field of electronic appliances, it is mainly used to manufacture various wires and cables, battery electrodes, printed circuit boards, etc; In medical materials, due to its heat-resistant, water-resistant and non-toxic properties, it can be used as materials for various medical devices and artificial organs, such as artificial blood vessels and artificial hearts; It can be used as release agent and non sticky cooker in plastic processing and food industry.
