TECASINT 4121 black

polyimide with 15 % graphite

TECASINT 4121 is based on the base polymer TECASINT 4111, plus 15% graphite. The material is particularly suitable for tribological applications thanks to its improved friction and wear behaviour. Thanks to its self lubricating property, TECASINT 4121 is well suited to dry applications.
