TECASINT 2021 black

Polyimide with 15% graphite

TECASINT 2021 is a plastic reinforced with 15 % graphite and based on the base polymer TECASINT 2011. It is particularly suitable for tribological applications owing to its improved friction and wear behaviour. Thanks to its self lubricating property, TECASINT 2021 is well suited to lubricated and dry applications.
