CELAZOLE (Polybenzimidizole PBI)

Unfilled Celazole® PBI (U-60) – The highest performing engineering plastic, polybenzimidazole (PBI) is ideally-suited for use in the most extreme engineering applications.

Material Availability

  • Compression molded Rod
  • Compression Molded Tubing
  • Compression Molded Plate
  •  Injection Molded Shapes (T-Series only)
  • Extruded Shapes (T-Series only)
  • Tight Tolerance Machined Components
  • Custom Bearings and Wear Components
  • Custom Gears

At temperatures over 400°F (205°C), PBI exhibits the highest strength and stiffness of any unfilled plastic. It is even capable of withstanding brief exposure to temperatures as high as 1400°F (760°C) and performs best in an oxygen-free environment.

Celazole Plastic Part
  • Excellent hardness
  • Low coefficient of friction
  • Outstanding Tg and heat deflection temperature
  • Relatively low coefficient of thermal expansion
  • High volume resistivity
  • Very good plasma resistance
