Material Data Sheet
Material: Nylatron GSM
Molybdenum Disulphide (MoS2) Filled PolyamideNylatron® GSM is similar to Nylatron® GS except Nylatron® GSM is made up of small participles of molybdenum disulphide (MoS2). This increases the load bearing capacity will keeping the impact resistance similar to that of Nylon. This material is most commonly used for gear, sheaves and sprockets.
