Low friction plastic with strong chemical, high temperature and weathering resistance

PTFE

PTFE (polytetrafluoroethylene) is a flexible, low-friction fluoropolymer known for its exceptional resistance to chemicals and weathering. It remains stable at temperatures as high as 500ºF, making it ideal for use in high-temperature settings.

Additionally, PTFE possesses excellent electrical insulating capabilities. It is available in various formulations, including unfilled, glass-filled, and bearing grades.
