Torlon PAI 4203 rod
1.The introduction of PAI material:
PAI polyamide-imide is a modified polyimide, it is a heat resistant amorphous engineering thermoplastic,primarily by trimellitic anhydride and various aromatic diamine condensation.From temperatures of 500°F to chemically harsh environments,TORLON® outperforms similar materials in a broad range of applications.This melt processible plastic offers exceptional toughness,stiffness and strength and is both impact resistant and extremely durable.Available at a lower cost than many advanced engineering plastics,TORLON® can be machined to tight tolerances,extruded and compression molded.
