Torlon is a high-performance plastic that offers resistance to elevated temperatures, stress, and creep. It also has excellent mechanical strength characteristics, making it a popular choice for applications across a range of industries.

What is Torlon®/PAI?

Torlon polyamide-imide (PAI) is a high-performance thermoplastic that offers the optimal combination of temperature resistance and melts processability. Its impact and abrasion resistance along with its ability to carry high loads over a wide range of temperatures make it a popular material choice for wear applications and structural components. Engineers around the world prefer Torlon over other thermoplastics and comparable metals because of its many favorable characteristics, including:

Torlon®

  • Resistance to chemical damage

Torlon®/PAI Applications

Torlon material is used across multiple different markets and industries. Some of the most common applications for Torlon parts and components include:

  • Natural gas compressor components
  • Torlon-PAIElectrical connectors
  • Insulators
  • Fasteners
  • Labyrinth seals
  • Linkages
  • Nests
  • Bearing components
  • Pump parts and systems
  • Sealing rings
  • Sliding compressor vanes
  • Sockets
  • Test sockets

Torlon®/PAI Machining Considerations

Different materials often have various design, manufacturing, and end-use constraints that both product designers and manufacturing experts need to account for. Because of Torlon’s positive characteristics, manufacturers can work with the material to reliably produce complex and precise components. Some of the considerations for machining Torlon include:

  • Low expansion coefficient. Torlon remains dimensionally stable throughout the machining process and won’t expand or contract unpredictably due to higher temperatures.
  • Ease of use. Torlon is easy to fabricate and machine using various processes.
  • Excellent strength characteristics. Torlon offers excellent fatigue, impact, and mechanical strength properties, making it ideal for extreme working conditions.
  • Resistance to Damage. Torlon can resist damage from creep and wear and is also resistant to various chemicals, including acids, mild bases, gasoline, and more.
  • Heat Resistance. Torlon can safely be used across a wide temperature range from cryogenic temperatures up to 500° F. It also has great thermal stability and low flammability and generates low levels of smoke.
  • Customization Possibilities. Torlon can be combined with additives to enhance certain characteristics. For example, fabricators can add glass to the formula to increase the material’s load capacity.

Every project’s material needs are different. Work with an experienced manufacturing service that can help you determine if Torlon/PAI is the right fit for your project.
