PA 6.6 MoS²

PA – Polyamide

PA 6.6 MoS²

PA 6.6 MoS² is a PA 6.6 that contains molybdenum disulphide. This additive gives material sliding characteristics that are considerably better than those of pure PA 6.6. The additive also improves the material’s resistance to UV radiation. We deliver PA 6.6 MoS² as plastic sheets, rods and as hollow rods.
