| Torlon 4645 is an injection moldable wear-resistant polyamide-imide (PAI) resin that mainly provides excellent wear resistance for lubricating wear products. At 275 ℃( 525 °F), Torlon PAI has more strength and rigidity than all thermoplastics, and has excellent wear resistance, creep resistance and chemicals. Potential applications of Torlon 4645 polyamide-imide include thrust washers, seals, sliding vanes, spools, bushings, clutch rollers, and pistons. |
