Technical Information

Celazole PBI (Polybenzimidazole)
Celazole PBI offers the highest temperature resistance and best mechanical property retention of all unfilled termoplastics. Thanks to its unique property profile, Celazole PBI might bring the ultimate solution when no other plastic material can. It is a very appealing material to high-tech industries such as semiconductor, aircarft and aerospace industries.

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)

Celazole PBI
(Colours: Black only)
Polybenzimidazole 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”.
