Torlon® Polyamide-imide (PAI)/Applications


>

Torlon® takes the properties of strength, heat tolerance, and wear resistance to the highest levels currently possible for plastics, and costs less than many alternative high end materials. Typical applications include:


  • Aircraft hardware
  • Transmission and power train
  • Electrical/Electronics
  • Semiconductor fab
  • Oil and gas exploration
  • Bearings and retainers
  • Gears
  • Bushings and Seals
  • Thrust washers

Torlon has the highest strength and stiffness of any thermoplastic up to 275°C (525°F); features grades that are wear resistant in dry or lubricated environments; and, is resistant to creep, corrosion and chemicals – including strong acids and most organics. It has terrific thermal and dimensional stability, machines like steel and can be molded into complex geometries. It comes in non-conductive and semi-conductive grades. A truly remarkable polymer!

Transmissions & Hydraulics

Thermal and dimensional stability , high compressive strength and creep resistance make Torlon a solid choice for thrust washers and transmission balls in under-the-hood automotive applications. Resistance to solvents and high friction coefficients allows Torlon poppets and bearings to work well in dry or lubricated environments.



aerospace_ring

Light weight, strong and corrosion resistant with sustained use temperatures to 275°C (525°F), Torlon is used in the aerospace industry to replace metal, and in electrical applications requiring non-conductive or semi-conductive materials.


vacuum_pump

Torlon's low coefficient of friction in lubricated and non-lubricated conditions coupled with its rigidity, thermal stability and resistance to fatigue extend the life of sliding vanes and impellers and improves pump performance.


Gears

torlon_gears

Gears in high temperature, dry or lubricated environments, such as on business machines can benefit from Torlon's dimensional and thermal stability, wear resistance and strength.

Bearings & Retainers

Lightweight, load bearing, high friction coefficient, self lubricating: properties that make for excellent bearings and bearing retainers.


Temperatures inside business machines and electrical devices can reach levels in excess of 200° C.

With thermal expansion characteristics similar to steel, Torlon dissipates heat and will not distort, warp or fatigue at elevated temperatures. Torlon components maintains dimensional integrity, resist wear and creep, and are non-conductive making them ideal for electrical applications.


Near Net Shapes

Machining a finished part from a block of plastic can be costly and wastes material. Injection molding a slightly oversized part (i.e. near net shape) that can be machined to tolerance saves time and money. Often only one or two dimensions will need a final touch up.


Seals and Bushings

Torlon's superior wear characteristics and conformability (non-leaking) insures long life for seals and bushings in harsh applications.
