TECASINT 8061 yellow-brown

PTFE with 40 % polyimide

TECASINT 8061 has been made from PTFE with a modification of 40 % PI. Compared with TECASINT 8001 it has a lower creep tendency under load, along with outstanding sliding and friction properties. The material is ideally suited to soft mating materials e.g. stainless steel, brass, aluminium or bronze.
