Duratron® PBI Family of Products
Duratron® PBI is the highest performance engineering thermoplastic available today. It offers the highest heat resistance and mechanical property retention over 205 °C (400 °F) of any unfilled plastic. It has better wear resistance and load carrying capabilities at extreme temperatures than any other engineering plastc, reinforced or not. As an unreinforced material, Duratron® PBI is very "clean" in terms of ionic impurity and it does not outgas (except water). These characteristics make this material very attractive to semiconductor manufacturers for vacuum chamber applications. Duratron® PBI has excellent ultrasonic transparency which makes it an ideal choice for parts such as probe tip lenses in ultrasonic measuring equipment. Duratron® PBI is also an excellent thermal insulator. Other plastics in melt do not stick to it making it ideal for contact seals and insulator bushings in plastic production and molding equipment.

Duratron® PAI Family of Products
Duratron® PAI is a family of the highest performing, melt processable plastics, characterized by superior resistance to elevated temperatures. These plastic grades are capable of performing under severe stress conditions at continuous temperatures to 260 °C (500 °F). Parts machined from Duratron® PAI stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics. An amorphous material with a Tg (glass transition temperature) of 537°F (280°C), Duratron® PAI's extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire service range. A post-curing cycle is sometimes recommended for components fabricated from extruded shapes where optimization of chemical resistance and/or wear performance is required. For large shapes or custom geometries like tubular bar, compression molded Duratron® PAI shapes offer designers the greatest economy and flexibility.
Common applications of Duratron® PAI products include electrical connectors, bearing cages, mandrels, chip nests and sockets, and labyrinth seals.
