NYLON

Nylon is one of the most widely used and versatile thermoplastic resins. Its combination of physical properties and reasonable price make it a favorite choice for numerous applications. Nylon's toughness, wear resistance, tensile strength and lubricity make it a good choice for many mechanical machine parts.

Nylon has a consistent history of replacing other materials including: metal, brass, bronze, aluminum and rubber. In replacing metal gears in machinery, nylon can be advantageous because of its ability to reduce noise, use less lubrication and increase gear life. Nylon can be fabricated on most mills with high precision.

TYPE 6 (Cast Nylon)
This nylon exhibits all the properties which generally make nylon a superior engineering material: high strength, low friction and wear resistance. However, because of the casting process, part size and thickness are almost unlimited without degradation of the material's internal structure. Cast nylon meets FDA standards. It is also available in blue, glass-filled and molybdenum-disulfide filled grades.

TYPE 6/6
This standard nylon is characterized as having an excellent combination of physical properties including: a high melting point, resistance to repeated impact, low coefficient of friction and resistance to abrasion. It has good resistance to fuels, lubricants and most chemicals, but is attacked by phenols, strong acids and oxidizing agents.

TYPE 6/12
This nylon is the low moisture absorption grade of nylon.

TYPE MD (Molybdenum Disulfide Filled Nylon)
A filled nylon 6/6. The addition of particles of molybdenum disulphide enhance the lubricity of this product over unfilled nylon. In applications requiring high lubricity, this material may be a good candidate. In addition to greater lubricity, other property enhancements that occur are: low surface friction, increased heat resistance, higher tensile properties and improved dimensional stability.
