Celazole PBI
Polybenzimidazole

Main characteristics:

• Extremely high maximum allowable service temperature in air (310°C continuously, going up to 500°C for short periods of time)
• Excellent retention of mechanical strength and stiffness over a wide temperature range
• Extremely low coefficient of linear thermal expansion
• Excellent wear & frictional behaviour
• Inherent low flammability
• Good electrical insulating and dielectric properties
• Low outgassing (dry material)
• High purity in terms of ionic contamination
• Excellent resistance against high energy radiation (gamma and X-rays)

Each material is normally available in rod, sheet, plate and tube and in most cases can be purchased cut to size – for a summary of availability, click here.

Offers the highest temperature resistance and best mechanical property retention of all unfilled thermoplastics. CELAZOLE PBI is very “clean” in terms of ionic impurity and does not outgas (except water). These characteristics make this material extremely attractive to high-tech industries e.g. semiconductor and aerospace industries. Usually CELAZOLE PBI is used for critical components to decrease maintenance costs and to gain valuable production “uptime”.
