GENERAL DESCRIPTION Nylon is one of the most widely used plastics in the world, especially as a bearing and wear material. Nylons are frequently used as replacements for bronze, brass, aluminum, steel and other metals, as well as other plastics, wood, and rubber.
Nylons offer extremely good wear resistance, coupled with high tensile strength and modulus of elasticity. They also have high impact resistance, a high heat distortion temperature, and resist wear, abrasion, and vibration. In addition, nylons can withstand sustained contact with a wide variety of chemicals, alkalies, dilute acids or oxidizing agents.
Another important factor, both economically and mechanically, is the relative light weight of nylon -- approximately 1/8 the weight of bronze, 1/7 the weight of cast iron, and 1/2 the weight of aluminum -- which reduces both the inertial and static loads and eases the handling of large components during maintenance or replacement procedures.
REPRESENTATIVE EXTRUDED NYLON GRADES Nylon 101 - Extruded Nylon 6/6
Of all the unmodified nylons, this grade is the strongest, most rigid, and has one of the highest melting points. This material is available in natural (off-white) and black colors, and custom coloring is available. The natural grade is FDA, USDA and 3A-Dairy compliant and is primarily used for food contact parts.
Nylatron® GS - Extruded Moly-Filled Nylon 6/6
Finely divided particles of "Moly" (molybdenum disulfide -- MoS2) are dispersed evenly throughout the nylon material during polymerization. The Moly particles act as a dry lubricant to enhance nylon's load bearing and wear capabilities while offering improved strength and rigidity. With a lower coefficient of linear thermal expansion than unfilled nylon, Moly-filled nylon maintains better fit and clearances, and has less tendency to seize as bearings.
30% Glass-Reinforced Extruded Nylon 6/6
For applications requiring higher compressive strength and rigidity, and/or improved frictional characteristics 30% glass reinforced nylon 6/6 is also available.
