Torlon: Your Next Solution

Torlon is like no other plastic. Made out of trimellitic anhydride and aromatic diamines, Torlon plastic is a polyamide-imide (PAI) and a non-crystalline thermoplastic. It is the highest-performing thermoplastic that is still melt processable.

What does this mean for engineers, product developers and manufacturers? It means Torlon has many advantages over other plastics and can be used in a variety of purposes.

Ready for tough jobs, Torlon is unmatched by other plastics.

  1. Torlon has a high heat distortion and continuous service temperature. It has more strength at high temperatures than other engineered plastics do at room temperature. In fact, it can perform at 500°F and has a glass transition temperature of 537°F.
  2. Torlon comes in multiple variations, each with unique benefits. For example, Torlon 4203 has great compressive strength and electrical insulation.
  3. This high performance plastic is extremely durable. You can use Torlon to create high impact resistant and corrosion resistant products, reducing replacement and labor costs.
  4. Torlon is also chemical resistant. For the most part, it is not affected by chemicals such as aliphatic and aromatic hydrocarbons, and chlorinated and fluorinated hydrocarbons. Even most acids do not impact Torlon at moderate temperatures.
  5. Torlon is flame-retardant. In fact, Torlon is popular in the aerospace industry because it satisfies the industry’s strict flammability requirements.

With all these exceptional properties, Torlon can often replace metal. Unlike many other plastics, Torlon is tough enough to do the jobs conventionally done by metals with additional benefits. For example, Torlon is half the weight of Aluminum. This can make products lighter without impacting functionality. (Lighter moving parts also often means an increase in mechanical efficiency.) Moreover, Torlon can be injection molded, compression molded and machined into final forms. Because injection molding is low-cost, you can save time and money by utilizing Torlon. Lastly, if you are simply looking for a quieter alternative to metal, Torlon is a great option.

With its mechanical strength and durability, Torlon plastic is suitable for high stress situations. This high-performing plastic can be found in the aerospace industry, semiconductor manufacturing, turbomachinery and chemical process pumps. Torlon 4203 (electrical grade) is a great material for electrical connectors and insulators, while Torlon 4301 (bearing grade) is often used for non-lubricated bearings, bearing cages and reciprocating compressor parts. Torlon 5530 (glass-reinforced grade) is suitable for rotors, insulators, impellers and bum-in sockets.

If you need a Torlon vendor, we can help. Aztec Plastic received Approved Vendor Status from Solvay Advanced Polymers for molding and machining Torlon. Our Torlon screws are often used in high voltage isolation, thermal isolation, rectifiers, and high and low voltage inverter parts. We use Torlon to solve problems in various industries. For instance, we produce higher-performing and longer-lasting poppets and spools using Torlon to fight the common leakage problem in hydraulic power systems.
