Nylon was the first engineering resin. It has been used in applications ranging from electronic, marine, and automotive industries to fibers used to make carpet. Nylon has outstanding wear resistance and low frictional properties. It has very good temperature, chemical, and impact properties. However, nylon's one weakness is a propensity to absorb moisture and thus have poor dimensional stability.
These crystalline plastics are available in many compositions, ranging from molding and extrusion materials to solution and fluidized bed coatings and casting resins. The crystalline structure of nylons, which can be controlled to some degree in processing, affects stiffness, strength and heat resistance, but at the sacrifice of tensile strength and stiffness. Nylons that have not been compounded with UV stabilizers are sensitive to ultraviolet light. These compounds should not be used for extended outdoor service. Carbonblack is the most effective of the UV stabilizers. These additives also increase tensile strength and hardness and decrease ductility and toughness slightly. Low friction, good abrasion resistance and the ability to operate without lubrication, qualify the nylons for such applications. Although lubrication improves the performance of nylon bearings and wear surfaces, only intermittent lubrication is required.
Good mechanical properties and resistance to heat and fuels
make these materials suitable for mechanical and electrical
hardware and under-the-hood components. Examples are:
• Timing sprockets
• Speedometer gears
• Cooling fans
• Wire connectors
• Windshield wiper parts
• Door-latch hardware
• Molded fender extensions
• Steering-column lock housings
• Brake fluid reservoirs
In addition, nylon parts are used in:
• Business machines
• Industrial equipmentCast Nylon -Please Call for Pricing and Availability
Parts machined or fabricated from cast nylon are light weight and corrosion resistant. In addition, cast nylon's excellent load bearing capability, wear resistance and impact resistance make it ideal for demanding construction environments. As a material of proven value in the field, cast nylon is found in a large variety of equipment in numerous components.
