Duratron® PBI

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.
