Duratron PBI: Sheets, Rods & Tubes

Duratron PBI (previously known as Celazole PBI) offers the highest temperature resistance and best mechanical property retention of all unfilled thermoplastics.

Thanks to its unique property profile, Duratron PBI might bring the ultimate solution when no other plastics material can.

As an extremely hard advanced engineering plastic, Duratron PBI is suitable for friction and wear applications. It's extreme temperature resistance (up to 310°C continuously) means Duratron PBI can be used where other advanced engineering plastics cannot.

Duratron PBI rods and plates are used in high-tech industries such as semiconductor, aircraft and aerospace.

 

 

 


Duratron PBI (Celazole PBI) 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, 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 purity level in terms of ionic contamination
  • Excellent resistance against high energy radiation (gamma & X-rays)

Celazole PBI is extremely hard and can be challenging to fabricate. Polycrystalline diamond tools are recommended when fabricating production quantities. Celazole tends to be notch sensitive. All corners should be radiused (0.040" min.) and edges chamfered to maximise part toughness.

High tolerance fabricated components should be stored in sealed containers (usually polybags with desiccant) to avoid dimensional changes due to moisture absorption. Components rapidly exposed to temperatures above 400°F (205°C) should be "dried" prior to use or kept dry to avoid deformation from thermal shock.
