SMR-0454 & SMR-0747

High modulus, low elongation, high compressive strengths and low creep — these products provide them all. Graphite-filled for low friction, SMR-0454 and SMR-0747 offer the same thermal resistance as the SP products, with less deflection under load. The addition of carbon fibers in SMR-0454 gives extra benefits: a steel-like coefficient of thermal expansion and better thermal conductivity.

Fiber-reinforced polyimide resins ideal for:

  • Bushings
  • Washings
  • Bumper pads
  • Seal plates
  • Pulleys

Benefits

  • Self lubricating
  • Ideal for high-friction, high-temperature, highly-oxidative environments
  • Lighter weight than aluminum
