Compliance Info

Slide 1 of 1, currently active

General Info

TECASINT® 2021 is a PI Polyimide that contains 15% graphite and is also available for applications requiring improved wear resistance & lower coefficient of friction. It is particularly suitable for tribological applications owing to its improved friction and wear behavior. Thanks to its self lubricating property, TECASINT 2021 is well suited to lubricated and dry applications.
