Quadrant EPP Broadens Torlon® PAI Product Lineup

Share Article

More Sizes and More Shapes of Torlon® PAI Machining Stock Now Available from Quadrant

Engineers and designers will have more options for new or upgraded part designs with Quadrant’s expanded range of Torlon® PAI shapes. Torlon is an ideal material for applications where extreme strength, stiffness, stability and wear-resistance are required. It is far more economical than most grades of PI and of-fers better performance in applications up to 500° F (260° C). Quadrant has exclusively produced Torlon 4203 PAI and Torlon 4301 PAI rod and sheet for several years. More and more engineers are recognizing the performance benefits of Torlon and are im-pressed by its value. Quadrant has been working to provide the material performance, sizes and shapes that this increasing interest is generating.

Quadrant is adding several larger rod diameters - up to 5.0” diameter for the electri-cal/structural grade of 4203 and up to 2.5” diameter for the bearing grade 4301. These larger diameters markedly improve yields for parts that were previously machined form sheet, and the machining of rods gives fabricators an opportunity to increase productiv-ity.

In addition to the new sizes, a new capability to provide tube in 4203 and 4301 up to 4.0” O.D. offers additional material and machining productivity gains. These new sizes and productivity enhancing shapes offer engineers more options for high performance and severe service bearing applications where Torlon’s strength, temperature and chemical resistance are necessary.
