  Polytetrafluoroethylene (PTFE) is one of the resins in fluoroplastics, which has great application value in mechanical, chemical, aerospace and military fields. Therefore, in-depth study on the structure and physicochemical properties of PTFE, especially through chemical and physical modification to develop new PTFE materials with excellent comprehensive performance, has become the main direction of research and development of PTFE. Filling modification is one of the commonly used modification methods of PTFE. Its filling process, filler quality and the combination of filler and PTFE matrix resin are the keys to improve and enhance the performance of PTFE.

Basic characteristics of polytetrafluoroethylene

• High temperature resistance

Operating temperature up to 250 ° C.

• Low temperature resistance

Good mechanical toughness; 5% elongation can be maintained even if the temperature drops to - 196 ° C.

• Corrosion resistance

-For most chemicals and solvents, it is inert and resistant to strong acids and alkalis, water and various organic solvents.

• Weather resistance

-There is an aging life in plastics.

• High lubrication

It is the friction coefficient of solid materials.

。 Non adherence

The first is the minimum surface tension in solid materials, which does not adhere to any substance.

• No poison

- Physiological inertia, no adverse reaction after long-term implantation as an organ
