PA – Polyamide


PA 6 FRT is a flame-retardant nylon. It combines good wear- and sliding‑related properties with strength and resistance to chemicals. It meets the requirements of the FAR 25.853 and EN 45545 standards and is widely used in the aviation and rail transport industries. The material is also UL94 V0-approved. We deliver PA 6 FRT as plastic sheets and bars.
