TECAMID™ 66 Nylon

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.

TECAMID® has an excellent balance of properties which make it an ideal material for metal replacement in applications such as automotive parts, industrial valves, railway tie insulators, and other industry uses whose design requirements include high strength, toughness, and weight reduction.

 Variety of TECAMID for Specific Applications

  • TECAMID™ 6/6
    Type 6/6 general purpose standard grade nylon. Extruded in natural and black. (Weather Resistant Black Grade is also available as a custom.)
  • TECAMID™ 6/12
    Type 6/12 nylon. This nylon has lower moisture absorpton rates than nylon 6/6, hence superior dimensional stability.
  • TECAMID™ ST
    Type 6/6 nylon. Super Tough nylon. Increased impact resistance and toughness over Tecamid™ 6/6.
  • TECAMID™ HS
    Type 6/6 nylon. Heat Stabilized nylon. Increased ability to withstand the negative effects of heat exposure and increased overall service temperature over Tecamid™ 6/6.
