CELAZOLE®

Best Mechanical Properties to 800°F (425°C)

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 semiconductor 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 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.

Advantages of Celazole

  • Highest mechanical properties of any plastic over 400°F (205°C)
  • Highest heat deflection temperature of any plastic at 800°F (425°C), with a 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 compressive strength of all unfilled plastics

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. It has better wear resistance and load carrying capabilities at extreme temperatures than any other reinforced or unreinforced engineering plastic.

Celazole* 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). Celazole is ideal for high heat bushings, connectors and valve seats. Celazole is extremely hard and can offer a challenge to fabricate. Fabrication instructions can be furnished by Quadrant EPP.
