Stiffness & Strength at Temperature Extremes

Product Profile:

  • Maintains strength with stiffness to 500°F (260°C)
  • Minimal expansion rate to 500°F (260°C)
  • Excellent wear resistance in bearing grades
  • Able to endure harsh thermal, chemical and stress conditions

Due to its versatile performance capabilities and proven use in a broad range of applications, Torlon polyamide-imide shapes are offered in extruded, injection molded, and compression molded grades.

In extruded or injection molded form, 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 use range. Torlon is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C). Extruded and injection molded Torlon stock shapes are post-cured using the latest technology and procedures developed jointly by Amoco Performance Products and DSM eliminating the need for additional curing by the end user I most situations. A post-curing cycle is recommended for components fabricated from extruded or injection molded shapes where optimization of chemical resistance and/or wear performance is required.

For large shapes or custom geometries like tubular bar, compression molded Torlon shapes offer designers the greatest economy and flexibility. Another benefit of selecting a compression molded grade is that resins are cured, or "imidized" prior to molding which eliminates the need to post-cure shapes or parts fabricated from compression molded shapes.

Popular extrusion and injection molding grades of Torlon are offered as compression molded shapes. Typically, you can identify a compression molded grade as having a second digit of "5" in the product name.
