Torlon® Engineered Plastics

Torlon® is a unique high performance plastic that can handle the toughest jobs. If your application requires strength at high temperatures, resistance to creep and wear, and the economies of injection molding, Torlon® engineering plastic can solve your design problem.

Strength and stiffness up to 500°F

Torlon® engineering resin can be used at temperatures well beyond the limits of most other high performance plastics. At high temperatures, Torlon® plastic is stiffer and stronger than many high performance materials are at room temperature.

Resistance to wear in high-friction use

Torlon® performance plastic is ideal for moving parts because it offers low wear, excellent creep resistance, and self-lubricity. In tests of wear resistance, the performance of Torlon® polyamide-imide is similar to that of more costly Vespel® polyimide1.

Low flammability and smoke generation

In tests of flammability, smoke density, and toxic gas emission, Torlon® polyamide-imide meets stringent aerospace requirements, and is used extensively in applications where flammability is a critical consideration.

Thermal and dimensional stability

Torlon® parts are reliable for long-term use at high temperatures. Torlon® parts hold their dimensions under loads and at high temperatures. Low coefficients of linear thermal expansion (CLTE) facilitate integration of Torlon® components with metal.

Resistance to harsh chemicals

Torlon® polyamide-imide is virtually unaffected by aliphatic and aromatic hydrocarbons, chlorinated and fluorinated hydrocarbons, and most acids at moderate temperature. It is attacked by saturated steam, strong bases and some acids at high temperature.

Impact resistance

Torlon® engineering plastic can absorb impact energy better than most other high modulus materials.

There are but a few molders of Torlon and AEP offers the world's largest selection of Torlon inserts, with a product line that is unmatched in the industry.

How Torlon® polyamide-imide compares with alternate materials

Torlon® polymers replace metal when other plastics cannot.
Few plastics are tough enough to replace metal, but Torlon, a non-metallic fastener, has been exceptionally successful in applications considered too severe for plastic.

Replacing metal with plastic opens low-cost fabrication options such as injection molding. Mechanical efficiency, gained from lighter moving parts, conserves energy. Vibration and noise are reduced, and rust is eliminated.

Some engineering plastics are not in our league.
Their strength, stiffness, and maximum service temperature fall far short of Torlon non-metallic fasteners. While these plastics are good enough for many applications, choose Torlon® plastic when a substantial margin of performance is desirable.

Torlon plastic fills a unique niche among high performance engineering materials.
Consider Torlon® polymers first if strength, stiffness, and resistance to high temperature are requirements of your application. When a combination of these properties is critical, Torlon® polyamide-imide will out perform polyethersulfone, polyetherimide, polyphenylene sulfide, and polyetheretherketone.

On a per-pound basis, Torlon composite fasteners may cost more than some of these competitive resins. But for that extra margin of performance, specify Torlon® engineering plastic. Request a quote for Torlon composite fasteners.
