Performance of polytetrafluoroethylene seal products
May 10, 2018

Polytetrafluoroethylene (PTFE) is the most suitable seal material in the sealing products industry, considering the high temperature resistance and chemical resistance. Pure polytetrafluoroethylene (PTFE) sealing products can reach the food level. Used in medical equipment or food processing equipment, pure polytetrafluoroethylene (PTFE) materials are harmless to the human body. Many of these materials are used in life, such as cup, lunch box, loop paper cup, electric rice cooker. Because polytetrafluoroethylene (PTFE) is not only high temperature resistant, but also self lubricating.

The performance of seal products has a great influence on the efficiency and performance of the whole machine.  Polytetrafluoroethylene (PTFE) material has the characteristics of corrosion resistance, aging resistance, low friction coefficient and non stickiness, wide temperature range and good elasticity, so it is very suitable for the manufacture of sealing products with high corrosion resistance and higher temperature than 100 C. Such as machine, heat exchanger, high pressure vessel, large diameter container, valve, pump groove flange seal products, glass reaction pot, plane flange, large diameter flange seals, shaft, piston rod, valve rod, worm pump, rod seal products and so on.

Pure polytetrafluoroethylene (PTFE) seals can not meet the requirements of some specific mechanical equipment, so we have developed a variety of materials to produce polytetrafluoroethylene (PTFE) seal products, so that the PTFE seal products can meet the requirements of machinery and equipment requirements. On the basis of polytetrafluoroethylene (PTFE) material, adding a certain proportion of copper powder, the production of the seal product is more wear-resistant than the pure polytetrafluoroethylene (PTFE) material, and if the carbon fiber is added, the product will be more lubricated. As long as the material of PTFE is added to the raw polytetrafluoroethylene (polytetrafluoroethylene) materials according to the requirements of the mechanical equipment, a seal product which is more suitable for the use of mechanical equipment can be produced.
