Nylon
Sustamid 66 GF30
SUSTAMID 66 is an extruded general purpose nylon (Polyamide 66). Nylon is one of the original engineering plastics and is still today the material of choice for many bearing and wear applications. Due to its unique combination of physical properties such as toughness, abrasion resistance, chemical resistance and light weight, SUSTAMID 66 is regularly machined into parts to replace bronze, brass, steel and aluminum. SUSTAMID 66 MoS is enhanced with molybdenum 2 disulfide and provides a lower coefficient of friction and improved wear resistance. SUSTAMID 66 GF 30 is reinforced with 30% glass fibers and offers higher tensile strength, flexural strength and superior abrasion resistance.
