Material Notes:
Celazole® polybenzimidazole (PBI) resin is a unique and highly stable linear hetrocyclic polymer. PBI is characterized by high strength; excellent thermal stability, and broad chemical resistance. Celazole® T-Series products combine the superior mechanical properties and thermal resistance of PBI with the melt process ability of polyaryletherketones.Designed for injection molding and extrusionCelazole TL-60 is a lube grade blend offering superior wear resistance, low friction, chemical resistance and high load bearing capability. Well-suited for rotor vanes, thrust bearings, plane bearings, bushings and other friction management applications – particularly under load.Information provided by PBI Performance Products
