DOCAFLON PTFE-CG25
A version of the “natural” PTFE reinforced with carbon and graphite. It has greater rigidity, dimensional stability, smaller creeping, it is electrically Esd material. Its wear resistance is better than that of “natural” PTFE.
Color:
black
Electrically insulator:
No
main area of use:
Exceptional gliding and wear-proof properties, Non-insulating applications (anti-static, ESD), Excellent chemical resistance
