PBI offers the highest heat resistance and mechanical property retention over 400°F on any unfilled plastic and has better wear resistance and load carrying capabilities at extreme temperatures than any other reinforced or unreinforced engineering plastic. PBI is a very 'clean' product 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 and has excellent ultrasonic transparency which makes it an ideal choice for parts such as probe tip lenses in ultrasonic measuring equipment. PBI is also an excellent thermal insulator and it is ideal for contact seals and insulator bushings in plastic production and molding equipment.
