KESTAMID-GRF®
- Chemical Family
- Polyamides
Kestamid-GRF® has a high degree of crystallinity and better hardness and compression strength properties compared to standard Kestamid®. It has a low coeffient of friction and a high degree of abrasion resistance. It has good weatherability and UV resistance properties and can be more easily mechanically machined compared to standard Kestamid®. It also can be used in higher temperatures compared again to the standard type.
