Duratron PBI (CU60): Sheets, Rods & Tubes
Duratron PBI (previously known as Celazole PBI) is a very appealing material to high-tech industries such as semiconductor, aircraft and aerospace due to its unique property profile.
Duratron PBI has an extremely high maximum allowable service temperature in air (310°C continuously, 500°C for short periods) as well as excellent retention of mechanical strength, stiffness and creep resistance, 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, high purity in terms of ionic contamination and excellent resistance against high energy radiation (gamma and X-rays).
Duratron PBI offers the highest temperature resistance and best mechanical property retention of all unfilled thermoplastics, meaning it will bring the ultimate solution where no other plastic material can.
Duratron PBI (Celazole PBI) Characteristics

- 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 out gassing in vacuum (dry material)
- High purity level in terms of ionic contamination
- Excellent resistance against high energy radiation (gamma & X-rays)
Duratron PBI (Celazole PBI) Technical Notes
Duratron PBI is extremely hard and can be challenging to fabricate. Polycrystalline diamond tools are recommended when fabricating production quantities. Duratron 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 poly bags 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.
