TECASINT 1021 black

polyimide with 15 % graphite

TECASINT 1021 black has been developed from the base polymer TECASINT 1011 natural. Unlike TECASINT 1011, however, it contains 15% graphite. The material has improved friction and wear properties for tribological applications. TECASINT 1021 is suitable for both lubricated and dry applications since it is self lubricating.
