POLYAMIDE 6 + MoS₂ (extruded) Nylatron GS

MoS2 is obtained by adding a material with a stiffness, hardness and better dimensional stability to the PA 6.6 to change some loss of impact strength. The dispersion of molybdenum disulphide in their molecular structure, resulting in increased degree of crystallization, thereby improving its properties of friction and wear.
