TECAMID® 66 MO grey

PA 66 with MoS2

The addition of molybdenum disulphide (MoS2) to PA66 nylon produces a material with improved sliding and friction properties. This is achieved as a result of the additive's structure, and its nucleating effect. This effect also increases the rigidity, hardness and dimensional stability of this filled PA 66. Conversely, the impact strength of the modified polyamide 66 is reduced.
