Superior polymer strength with thermal stability
Celazole® U-Series products are used in some of the harshest environments — ranging from oil fields to aerospace to semiconductor applications. Parts made from Celazole® U-Series polymer perform well when exposed to conditions too severe for most plastics, and outperform other materials like polyimide, polyamideimide and polyetheretherketone in many extreme environments.
Celazole® PBI (polybenzimidazole) 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.
HIGH TEMPERATURE PERFORMANCE
Celazole® PBI has a glass transition temperature of 800°F
HIGH STRENGTH
Highest compressive strength of any unfilled resin on the planet
CHEMICAL RESISTANCE
100% tensile strength after being submerged in motor oil at 200°F for 30 days
