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

Product Profile:
• Highest machanical properties of any plastic over 400°F (205°C)
• Highest heat deflection temperature of any plastic at 800°F (425°C), with continuous service    capability of 750°F (400°C) in inert environments, or 650°F (345°C) in air with short term exposure    potential to 1,000°F (540°C)
• Lowest coefficient of thermal expansion and highest comprehensive strength of all unfilled plastics.
