Material Information

Nylon 6 belongs to the cast nylon family of materials. Cast nylons offer the widest array of sizes or custom shapes of any thermoplastic. Nylons are a frequently used material as replacements for bronze, brass, aluminum, steel, and other metals, especially in bearing or wear applications. Nylons offer excellent wear and impact resistance, have high tensile strength and high modulus of elasticity, and have a high heat distortion temperature. They also resist wear, abrasion, and vibration. Nylons can also withstand a variety of chemicals, alkalis, oxidizing agents, and dilute acids. However, nylons do absorb moisture, so they are not recommended for wet applications. Because of its high crystalinity, Nylon 6 has better heat deflection, better solvent resistance, better hygroscopic characteristics, and better dimensional stability than Nylon 6/6. Nylon 6 is available in rod, tube, and sheet.

Nylaton® GSM is a cast moly-filled grade of Nylon 6. The moly particles that are dispersed through the nylon material act as a dry lubricant to enhance load bearing and wear capabilities while maintaining impact strength and toughness. It is available in a dark grey color. The material is produced in larger thickness sheets and larger diameter rods than the similar property extruded material Nylatron® GS.
