CELAZOLE® PBI offers the highest temperature resistance and best mechanical property retention of all unfilled thermoplastics. Thanks to its unique property profile, CELAZOLE® PBI might bring the ultimate solution when no other plastics material can. It is a very appealing material to high-tech industries such as semiconductor, aircraft and aerospace industries.

Main characteristics:

  • extremely high max. allowable service temperature in air (310°C continuously, going up to 500°C for short periods of time)
  • excellent retention of mechanical strength, stiffness and creep resistance over a wide range of temperatures
  • extremely low coefficient of linear thermal expansion up to 250°C
  • excellent wear and frictional behaviour
  • inherent low flammability
  • good electrical insulating and dielectric properties
  • low outgassing in vacuum (dry material)
  • high ionic purity level
  • excellent resistance against high energy radiation
