Torlon 4435 polyamide-imide resin is specially developed for non-lubricating products with very low friction resistance in high pressure and high speed (PV) environments. Torlon 4435 is not only especially suitable for products that cannot be lubricated or do not need lubrication, but also provides additional safety margin for lubrication systems that have lost lubricating oil. The material has outstanding bending strength and compressive rigidity ranging from low temperature to high temperature, and can be used for products that need to bear weight. The coefficient of thermal expansion is low and has the ability to meet tight tolerance requirements in a wide temperature range. Due to its electrical dissipation characteristics, this brand can also be considered for anti-static purposes. Torlon 4435 can be specifically used for thrust washers, sealing rings, sliding blades, spools, bushings, clutch rollers and pistons. It can be injection molded into complex shapes.

| 1 . | Previously, ASTM standard test method D1708 was used to measure the tensile properties of PAI and similar materials because small samples can save more materials. The most widely used now is the ASTM D638 1 Bar specimen. The D1708 value contained is only used as a historical reference and is not used for comparison with the D638 value. |
