| NYLON (Click for Properties & Specs) Back to the Materials Group main page. Nylon thermoplastics offers design engineers and fabricators a range of properties to meet demanding application requirements in many industries. Nylon is extremely strong, tough, and abrasion resistant. It also exhibits self-lubricating characteristics. Other important characteristics on nylon are its impact resistance, mechanical strength, resilience, good electrical properties, dimensional stability at high temperatures and resistance to a variety of chemicals. This matrix of desirable properties allows nylon to perform in diverse and often severely demanding applications. Many times, nylon is found to perform successfully where metals and other materials fail or require frequent service. Nylon mill shapes are easily fabricated. When matched through careful design evaluation with appropriate applications, nylon mill shapes provide users with tough, strong, high performance parts highly suited to their purposes. General Purpose Nylon Nylon-GP is a type 6/6 nylon that exhibits these basic nylon properties: low friction, high strength, toughness and good abrasion resistance. It is the most widely used nylon. Compared with other modified nylons, it is structurally the strongest over the widest range of temperature and moisture, and has the highest melting point. Nylon-GP ( natural ) meets FDA standards. This combination of properties makes Nylon-GP useful for diverse industrial applications and it can replace many metals and other materials in many uses. Nylon-GP will outwear steel in many applications. Nylon 6/6 is available in natural and black. Key Properties: high wear and abrasion resistance
high strength low coefficient of friction characteristics
self-lubrication characteristics noise dampening
characteristics good electrical insulation resistance
to alkalies and organic chemicals easily machined
light weight
Uses: wear plates gears
bushings & bearings rollers guides
pulleys and many more.
Glass Reinforced Nylon Glass-fiber reinforced nylon combines high strength with the basic nylon properties. Overall, mechanical properties and dimensional stabilities are enhanced in this tough material. Specific property advantages include increased tensile strength, better creep resistance, and a higher modulus of elasticity. Parts designed using glass reinforced nylon will exhibit high fatigue endurance, low deformation under load and good impact strength. Key Properties: greater tensile strength
increased modulus of elasticity improved creep
resistance greater dimensional stability
Uses: gears, bearings, bushings requiring
high load strength parts requiring greater rigidity
close tolerance, precision parts
