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.
There
are several other grades of Torlon available. Please contact Alro Plastics
for additional information.
