PBI CELAZOLE® POLYBENZIMIDAZOLE

POLYBENZI MIDAZOLE PBI-CELAZOLE® Key Facts

Celazole® polybenzimidazole (PBI) resin, is a unique organic polymer which does not burn in air and has extraordinary high-temperature resistance, along with excellent stability to chemicals and hydrolysis. Celazone is ideal for applications where requirements cannot be met by other resins at extremely high temperatures, in harsh chemical environments, or in applications where durability and wear resistance are important. Parts molded of Celazole PBI are being used in gaskets, seals, O-rings, and valves in down-hole geothermal, petrochemical and industrial applications. They are also being evaluated in demanding aerospace applications requiring outstanding mechanical properties and short- term high-temperature resistance.

Key Features of CELAZOLE® POLYBENZI MIDAZOLE PBI

  • Highest glass transition temperature and heat deflection temperature of any thermoplastic (800°F)
  • Highest compressive strength of any thermoplastic at elevated temperatures
  • Best mechanical properties of any high performance plastic at elevated temperatures
  • Low coefficient of thermal expansion
  • Superior fatigue resistance
  • Low coefficient of friction and good wear behavior without added lubricants
  • Extremely high tensile and flexural strength versus other thermoplastics
