Torlon® polyamide-imide (PAI) 

More Staying Power at Top Temperatures

For over 30 years, Torlon® PAI has been recognized for long-lasting performance in severe service environments and a distinct combination of properties.

Key Features

• Exceptional long-term strength and stiffness up to 275°C
• Outstanding wear resistance
• Superior toughness from cryogenic up to 275°C
• Resistant to strong acids and most organics
• Inherent flame resistance
• Low CLTE

Typical Applications

• Aircraft hardware and fasteners
• Mechanical and structural components
• Transmission and powertrain components
• Coatings, composites, additives
• Electric motor components
• Semiconductor fabrication and testing
• Oil and gas exploration and recovery equipment
• Bearing retainers
• Gears
• Bushings
• Seals
• Thrust washers

High-strength grades of Torlon® PAI exhibit metal-like performance and are routinely specified for precision components used in repetitive-use, load-bearing operations. Glass-fiber and carbon-fiber-filled grades retain their strength and stiffness at high temperature with the added benefit of low creep and excellent fatigue resistance.

Wear-resistant grades Torlon® PAI deliver just the right combination of mechanical and tribological properties. This, combined with inherent heat and chemical resistance, makes them an effective alternative to metal in high-temperature friction and wear applications—even when lubrication is marginal or non-existent. Select grades can perform in lubricated environments at exceptionally high pressures and velocities (PV).

Torlon® resin can be processed using conventional injection molding techniques and offer a distinct processing advantage for high-volume production.

Torlon® resin is also available in extrusion and compression molding grades used to produce a variety of stock shapes for machining and low-volume production.

Powder grades of Torlon® PAI are specially designed to manufacture high-temperature adhesives, composite matrices, coatings and films.
