Product Description

TECASINT 4021 black POLYIMIDE WITH 15 % GRAPHITE

Starting with the base polymer TECASINT 4011, TECASINT 4021 with 15% graphite has been developed. Thanks to the improved friction and wear properties, TECASINT 4011 is particularly suitable for tribological applications. It is also suitable for dry applications since the material is self lubricating.
