Torlon® Polyamide-imide (PAI) 

Torlon® Polyamide-imide (PAI) delivers exceptional compressive strength and the highest elongation among Torlon® grades. It provides electrical insulation and outstanding impact resistance. With its high dielectric strength, this Torlon® grade is commonly used in IC test sockets, processors, electrical connectors, and insulators. Its ability to withstand high loads across broad temperature ranges makes it ideal for structural components like linkages and seals. Torlon® 4203 is also an excellent choice for wear applications involving impact loads and abrasive wear.
