Material Notes:
Duratron® PBI is the highest performance engineering plastic available from Quadrant EPP. It offers the highest mechanical properties of any thermoplastic above 400° F (205° C). Duratron® PBI is ideal for high heat bushings, connectors and valve seats. Duratron® PBI is extremely hard and can offer a challenge to fabricate. Fabrication instructions can be furnished by Quadrant EPP.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, 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 PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment.Data provided by Quadrant Engineering Plastic Products from tests on stock shapes and parts produced by Quadrant EPP. Formerly PBI Performance Products Celazole® PBI. Highest mechanical properties of any plastic above 400°F (204°C) Highest heat deflection temperature 800°F (427°C), with a continuous service capability of 750°F (399°C) in inert environments, or 650°F (343°C) in air with short term exposure potential to 1,000°F (538°C) Lowest coefficient of thermal expansion and highest compressive strength of all unfilled plastics
