Celazole® PBI (polybenzimidazole) is a high-performance, fully aromatic heterocyclic thermoplastic polymer known for its superior thermal and mechanical properties. With a glass transition temperature of 427°C, it offers exceptional strength and extensive chemical resistance, making it ideal for extreme environments. PBI powder can be compression molded into U-60 shapes, the highest performing base grade, which can then be machined into various parts. Additionally, PBI can be combined with polyaryletherketones (PEEK or PEKK) to create T-Series pellets suitable for injection molding and extrusion. PBI solutions are available for manufacturing hollow fiber membranes, flat sheet membranes, casting films, or coating metal surfaces.

Celazole® Features

  • Unmatched compressive strength among unfilled resins
  • Superior tensile and flexural strengthExcellent fatigue resistance and minimal creep
  • High hardness
  • Low friction coefficient
  • Exceptional glass transition (Tg) and heat deflection temperature (HDT)
  • Comparatively low thermal expansion coefficient
  • High volume resistivity
  • Excellent resistance to plasma
