Torlon Plastic

Injection Moldable, Unmatched Strength at High Temperatures
  • High performance, melt processable thermoplastic
  • An alternative to metal for a variety of components
  • Flame retardant, corrosion resistant

Torlon polyamideimide is the highest performance, melt processable thermoplastic available today. Aztec Plastic is the oldest existing processor of Torlon and one of the few companies that has experience with it in a wide range of applications. Extremely lightweight and strong, Torlon plastic can be extruded into shapes and injection molded into a variety of custom geometries. Its unique properties make it highly versatile and the chosen polymer for the aerospace, healthcare, automotive, industrial, agriculture, oil and gas, and other high performance industries.

Torlon properties

Torlon has more strength at temperatures up to 500°F than other engineered plastics do at room temperature and is more impact resistant at cryogenic temperatures than other high strength polymers. At moderate temperatures it is also extremely resistant to chemicals, including corrosive acids and most organics. It is virtually unaffected by aliphatic, aromatic, chlorinated, or fluorinated hydrocarbons.

In addition to being tough against organic and non-organic chemicals, Torlon plastic is half the weight of aluminum and quieter than metal. These qualities result in a lighter product that can increase mechanical efficiency, making Torlon an idea replacement for metal based components.

Torlon’s properties result from its transformation from a thermoplastic to a cross linked thermoset during an extended curing process. Glass reinforced and carbon fiber reinforced grades offer even greater stiffness and enhanced thermal expansion properties, while still remaining strong at high temperatures. These reinforced grades boast additional properties that are extremely beneficial: lightweight, and chemical resistant.


Types of Torlon plastic

Torlon plastic is available in many forms, and it provides a better solution for a variety of applications.

Torlon 4203 Used for electrical connectors and insulators and other high wear applications due to its high dielectric strength. Torlon 4203 Data Sheet, Torlon 4203L Data Sheet

Torlon 4275 A highly wear and chemical resistant grade, Torlon 4275 is perfect for bearings and thrust washers. Torlon 4275 Data Sheet

Industries using Torlon Plastic


Torlon is ideally suited for the aerospace industry due to its stability in both hot and cold environments, resistance to corrosive and oxidizing substances, low wear rates, low friction, ability to withstand high pressure, plus it’s lightweight.


Torlon’s high compressive strength, excellent creep resistance, and low wear rates make it a common choice for peristaltic pump rollers and bushings for prosthetics. Torlon components are also used in analytical instruments and medical devices.


Torlon wear and strength properties make it perfect for use in powertrains, cooling and heating systems, engine management systems, oil and fuel circuits, and transmission parts.


Put to work in the chemical engineering industry, Torlon’s resistance to various chemicals make it ideal for industrial equipment parts, pipes, pumps, fittings, and valves.


Because it’s half the weight of aluminum but as strong as traditional steels, Torlon is well suited for gears, wear pads, sheaves, housings, plug seals, nuts with gaskets, electrical components, and poppet valves.


Oil & Gas
Torlon is strong enough to handle the high pressure and heat common of oil & gas industry and down hole environments, making it popular for valve seats, connector bodies, seals, flappers, frac balls, and compressor valve components.


Consumer Products
In addition to heavier industries, Torlon is also regularly used in household goods like power and garden tools, textiles and fibers, as well as in various sports and leisure products.

Aztec Plastic has extensive experience working with Torlon. We were one of the first companies to ever process the material in the 1970’s when it was originally invented by Amoco. Over the decades, Torlon changed hands in ownership from Amoco to BP to Solvay Advanced Polymers, and Aztec was there during each transition. To this day, we continue to have Approved Vendor Status from Solvay Advanced Polymers for molding and machining Torlon.

We manufacture a wide variety of products for a range of applications using this material. Examples include our Torlon screws for high voltage and thermal isolation, rectifiers, and high and low voltage inverter parts, and Torlon poppets and spools fighting leakage problems in hydraulic power systems.
