Torlon®

With its versatile performance capabilities and proven use in a broad range of applications, Torlon®* polyamide-imide (PAI) shapes are offered in extruded, and compression molded grades.

Torlon® is the highest performing, melt processable plastic. It has superior resistance to elevated temperatures. It is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from Torlon® stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics.

Torlon® PAI’s extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire service range. Torlon® is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C). Torlon® stock shapes are post-cured using procedures developed jointly by BP Amoco and Quadrant. This eliminates the need for additional curing by the end user in most situations. A post-curing cycle is sometimes recommended for components fabricated from extruded shapes where optimization of chemical resistance and/or wear performance is required.

 

Torlon® 4203/4203L (Extruded)

Download Data SheetTorlon® 4203 polyamide-imide offers excellent compressive strength and the highest elongation of the Torlon® grades. It also provides electrical insulation and exceptional impact strength. This grade is commonly used for electrical connectors and insulators due to its high dielectric strength. Its ability to carry high loads over a broad temperature range makes it good for structural components such as linkages and seal rings. Torlon® 4203 is also an excellent choice for wear applications involving impact loading and abrasive wear.

For electrical or high strength applications.

Torlon® 4301 (Extruded)

Download Data SheetThis Torlon® PAI is primarily used for wear and friction parts. It offers a very low expansion rate, low coefficient of friction and exhibits little or no slip-stick in use. Torlon® 4301’s flexural modulus of 1,000,000 psi, is higher than most other advanced engineering plastics. This grade excels in severe service wear applications such as non-lubricated bearings, seals, bearing cages and reciprocating compressor parts.

For general purpose wear and friction parts.
