Torlon Thermoplastic Products 4301 Bearing Grade, 4203 Electrical Grade 4XG 30% Glass, 4XCF 30% Carbon Filled Rods  Sheets Balls   Torlon poly(amide-imide) exhibits exceptional physical and chemical properties. It can withstand continuous exposure at temperatures from 450ºF to 500ºF (230ºC to 260ºC). 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 attack by aromatic and aliphatic hydrocarbons, chlorinated and fluorinated hydrocarbons and most inorganic salts and acid solutions.   Typical Properties Torlon 4203 Exhibits superior electrical insulation at elevated temperatures and is primarily designed for structural, electrical, and electronic applications. In addition Torlon 4203 displays excellent resistance to radiation. Torlon 4301 Retaining the same basic physical and chemical properties as 4203, Torlon 4301 is designed for bearing and wear applications such as non-lubricated bearings, seals, valve and compressor parts, piston parts, and bearing cages. It is used where high strength, resistance to wear, resistance to elevated temperatures, and solvent resistance are important application requirements. Torlon 4301 has a very low coefficient of friction and exhibits little or no slip-stick in bearing applications.
