PTFE belongs to special engineering plastics and is the best corrosion resistance material in the world. It is known as “Plastic King”. The main features are high temperature resistance, corrosion resistance, high insulation, ageing resistance and self-lubrication. Its uses include aerospace, electronics, chemicals, machinery and equipment, food and medical, pump and valve pipelines, vehicles and ships, air compressors, etc., and become an indispensable material for solving many key technologies in modern industry.

There are many surface treatment methods for PTFE, such as sodium-naphthalene solution treatment, plasma treatment, electrolytic reduction, high-temperature melting treatment, radiation graft treatment, metal evaporation, and the like. Dongguan Teflon hydrogen press piston ring manufacturers, regardless of which treatment technology is used, are to improve the bonding characteristics of the surface of PTFE materials. After the surface treatment of the PTFE material by these methods, the selection of a suitable adhesive according to the working conditions can achieve the bonding of PTFE to PTFE, metal, plastic, rubber, cement and the like. Although the cost of RPTFE is higher than that of PTFE, the mechanical properties of RPTFE are excellent, which significantly improves the service life of the whole machine and reduces the maintenance rate, thus reducing the investment in the later cost. It is recommended to purchase RPTFE from the long-term benefit.

It is worth mentioning that although the mechanical properties of RPTFE will be significantly better than imported PTFE, the added reinforcing agent will reduce the chemical stability and insulation properties of PTFE. For some food, medical and chemical industries, pure PTFE is still needed. The imported PTFE has better performance than domestic PTFE and is suitable for high-end customers.
