High Performance > 300°F | Polyamidimide (PAI)

TECATOR TI5031 bearing grade PAI

TECATOR is a high performance melt processable polyamide-imide that maintains its excellent mechanical and wear properties in temperature environments exceeding 500°F. TECATOR TI5031 offers high PV capabilities in bearing applications, primarily at high loads and low speeds.

  • Excellent weather and gamma radiation resistance
  • Outstanding bearing and wear properties
    At elevated temperatures, TECATOR™TI5031 offers superior wear rates.
  • High strength and stiffness
  • Excellent electrical values
    TECATOR™TI5013 has a dielectric strength of 600 V/mil.
  • Good chemical resistance
    TECATOR™is not attacked by common solvents or fuels and is acceptable for use in contact with many acids.
  • Maintains a high proportion of mechanical properties over a broad temperature spectrum - cryogenic to 500°F.

TECATOR™(PAI) typical applications: Pump parts, valve seats, piston rings, seal rings, engine transmission parts and bearing cages. For the semiconductor industry it is used for "burn in" test sockets, nests, chassis and other applications such as welding nozzle tips.
