4301 Bearing Grade, 4203 Electrical Grade
4XG 30% Glass, 4XCF 30% Carbon Filled
Torlon poly(amide-imide) can withstand exposure at temperatures from 450°F to 500°F (230°C to 260°C). Torlon 4301 and 4203 resins provide better compressive strength and higher deflection temperature than most other high performance thermoplastics. Their low coefficient of thermal expansion and high creep resistance provide excellent dimensional stability over a wide range of temperatures. Chemically, Torlon resins are resistant to hydrocarbons, salts and acid solutions.
