Torlon® PAI

Torlon PAI MoleculeTorlon PAI has proven itself in a broad array of demanding applications in many industries: aerospace, vacuum technology, semiconductor, medical devices, cryogenics, electrical engineering, electronics and automotive.  PAI excels at applications that require strength at high temperatures and resistance to wear.

High-strength PAI grades perform similar to metals and are often used to make precision metal-replacement components that are used in repetitive load-bearing applications.  Grades that are reinforced by carbon fiber or glass fiber retain their strength and stiffness and have improved fatigue resistance and lower creep.  PAI is often used to make structural and dynamic components.

Wear-resistant grades offer good combinations of mechanical and tribological properties.  The inherent heat and chemical resistance of wear-resistant PAI grades makes them effective replacements for metals in high-temperature and wear applications, even without lubrication.  Certain grades can perform at exceptionally high pressures and velocities in lubricated environments.

To meet custom requirements, Torlon PAI can be compounded with a variety of fillers, reinforcements, additives and pigments.

Excellent compressive properties combined with creep and fatigue resistance make PAI a superior sealing material, engendering its use for seal rings, hydraulic poppets, brake tappets, check balls, thrust washers and compressor plates.
