TECAFORM® AH

TECAFORM® is a semi-crystalline thermoplastic offering high strength, stiffness and toughness. TECAFORM® is resistant to hot water, hydrocarbons and solvents, and it possesses good bearing and wear properties. It is available in natural and black grades. TECAFORM® is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability.

  • No centerline porosity
  • Low moisture absorption
  • Excellent machinability
  • Good combination of mechanical properties
  • Chemical resistance to fuels and solvents
    TECAFORM™ is resistant to aqueous solutions with pH values ranging from 4 to 14.
  • Good wear and abrasion properties
  • Good dimensional stability
  • Good property retention at elevated temperatures

TECAFORM® is used in a wide variety of industrial applications requiring good strength and toughness, dimensional stability, wear resistance and the ability to operate in a wet environment with little absorption. Material handling, machinery and fluid handling are some of the common industries utilizing TECAFORM®'s combination of properties. Typical applications are gears, wear strips, bushings, pump parts, fittings and rollers.
