Peek has excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. In industry, PEEK resin is used as raw material for manufacturing engine inner cover because of its good friction resistance and mechanical properties.
Teflon, namely polytetrafluoroethylene (PTFE), has the characteristics of high temperature resistance, acid resistance, alkali resistance and various organic solvents resistance. Polytetrafluoroethylene (Teflon) is easily worn by other materials because of its low intermolecular attraction and hardness.

Application of PTFE
1, Application of anticorrosion function
Including pipelines, exhaust pipes, steam pipes, rolling mills, high-pressure oil pipes, high-,medium-and low-pressure pipelines of aircraft hydraulic systems and cold-pressing systems, rectification columns, heat exchangers, kettle fabrics, towers and tanks, valves and other chemical equipment.
2. Application of low resistance function in load.
Comprise bearings, piston ring, machine tool guide rails and guide rings for chemical equipment, paper-making machinery and agricultural machinery; In civil engineering, it is widely used as bridges, tunnels, steel structures, large industrial pipelines and supporting sliders. As a bridge support and bridge rotation.
3. Application in electronic and electrical fields
Because of its inherent low loss and low dielectric constant, PTFE can be made into enameled wires, which can be used in micro motors, thermocouples, control equipment and so on. PTFE film is an ideal insulating material for manufacturing capacitors, radio insulating gaskets, motors and transformers, and it is also an indispensable material for electronic components in aviation industry.
4. Application in medical treatment and medicine
The expanded PTFE material is pure inert, has very strong biological adaptability, does not cause rejection reaction of the body, has no physiological side effects on the human body, can be disinfected by any method, has a microporous structure, and can be used in various rehabilitation projects, including artificial blood vessels and soft tissue regeneration patches, as well as blood vessels, hearts, general surgery and plastic surgery.
