Celazole ® TL-60 Lubricated PBI PEEK

Celazole® PBI is the world’s highest performance polymer for the most extreme applications.  Celazole® PBI (polybenzimidazole) U Series is a fully aromatic heterocyclic thermoplastic polymer that provides the ultimate in thermal mechanical properties and sets the standard for engineering polymer performance.  Characterized by its 427°C (800°F) glass transition temperature, high strength and broad chemical resistance, it’s meant for use in extreme environments. Celazole® PBI T-Series are blends of PBI with polyaryletherketones either (PEEK or PEKK).

U-Series

Celazole® PBI (polybenzimidazole) U-Series is a unique and highly stable linear hetrocyclic polymer. PBI is characterized by high strength; it exhibits excellent thermal stability, is hydrolytically stable after exposure to high pressure steam or water, is broadly resistant to hydrocarbons, alcohols, weak acids, weak bases, hydrogen sulfide, chlorinated solvents, oils, heat transfer fluids and many other organic chemicals.

T-Series

Celazole® T-Series products are PBI compounds that combine the superior mechanical properties and thermal resistance of PBI with the melt process ability of polyaryletherketones (PEEK or PEKK), which are available in glass, carbon and bearing grade blends for improved stiffness, wear resistance and other enhanced properties for specific applications.
