PTFE

(POLYTETRAFLUOROETHYLENE RESIN)
These materials can be used to make a variety of articles having a combination of mechanical, electrical, chemical, temperature and friction-resisting properties unmatched by articles made of any other material. Commercial use of these and other valuable properties combined in one material has established PTFE resins as outstanding engineering materials for use in many industrial and military applications. PTFE resins may also be compounded with fillers or reinforcing agents to modify their performance in use.

PTFE fluoropolymer resins are tetrafluoroethylene polymers, usually fabricated by cold forming and sintering techniques. PTFE resins have a continuous service temperature of 260°C (500°F). Much higher temperatures can be satisfactorily sustained for shorter exposures.

PTFE provides exceptional chemical, electrical, mechanical and thermal properties for a multitude of applications. It has one of the lowest dielectric constants and dissipation factors of any solid material. PTFE is almost totally unaffected by the chemicals usually encountered in commercial use.
