NYLATRON® NSM (CAST SOLID-LUBRICANT-FILLED NYLON 6)
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.
Nylatron® NSM is a cast solid lubricant filled nylon 6. This grade of nylon 6 offers the best wear resistance and lowest coefficient of friction, making it the best bearing and wear nylon product available. The solid lubricant additives make the material self-lubricating. In wear applications, Nylatron® NSM lasts 10 times longer than standard type 6 nylon.
