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.
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 plastics. It has better wear resistance and load carrying capabilities at extreme temperatures than any other reinforced or
unreinforced engineering plastic.
Advantages:
- Highest mechanical properties of any plastic over 400oF
- Highest heat deflection temp of any plastic at 800oF
- Lowest coefficient of thermal expansion of all unfilled plastics
- Highest compressive strength of all unfilled plastics
Applications:
- Insulator bushings
- Valve seats and seals
- Vacuum chambers
- Semiconductor parts
- Electrical connectors
- Clamp rings
