Physical Properties for Nylatron® GS Nylon

Nylatron® GS Nylon, Type 66, MoS2 filled, extruded

Material notes : Nylatron GS Nylon is a nylon and molybdenum disulphide (MoS2) composition designed to improve mechanical, thermal,

and bearing properties of type 6/6 nylon while maintaining its basic electrical and chemical characteristics. Through compounding, finely

divided particles impart extra lubricity to this nylon, permitting Nylatron GS parts to operate with little or no lubrication. The added lubricity

also contributes dramatically to component service life, making Nylatron GS a very cost-efficient choice. Nylatron GS nylon offers greater

wear resistance, lower surface friction, higher strength and greater rigidity than unfilled 6/6 with improved dimensional stability.
