PA 6.6 CF20

PA – Polyamide

PA 6.6 CF20

PA 6.6 CF20 is a PA 6.6 with a carbon content of 20%. The carbon fibre improves the material’s precision‑related properties, increases the acceptable temperature in use, and enhances the mechanical strength. Because of the additive, the material is electrically conductive (with a surface resistivity of 10^2–10^8 Ω) rather than insulating. We deliver PA 6.6 CF20 as plastic sheets and rods.
