Nylon 66 vs. Nylon 6 vs. PBT. Material Selection Guide.

A comparison of these high performance materials that can be used to choose between temperature resistance, strength, moisture absorption and more.

NYLON 66

  • High strength, stiffness and creep resistance
  • Good impact resistance
  • Good temperature resistance
  • Good friction and wear characteristics
  • Good chemical resistance to a wide range of chemicals, solvents, oils, greases, and fuels

Common Applications: Automotive, Air Bags, Conveyor Belts, Air Intake Manifolds, Tie Ropes

NYLON 6

  • High strength, stiffness and creep resistance (lower than nylon 66)
  • Good impact resistance
  • Good temperature resistance
  • Good friction and wear characteristics
  • Good chemical resistance to a wide range of chemicals, solvents, oils, greases, and fuels

Common Applications: Firearm Components, Automotive, Gears, Carpeting, Surgical Sutures

PBT POLYESTER

  • High strength, stiffness and creep resistance (lower than nylon 66)
  • Good long term thermo-oxidation resistance/resistance to yellowing
  • Good dimensional stability/low moisture absorption
  • Good electrical properties
  • Good chemical resistance

Common Applications: Electrical/High Energy Applications, Gear Wheels, Bumpers, Terminal Boards
