CELAZOLE® U-SERIES

HEAT RESISTANT POLYMER

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

Grades & Properties

U-Series

U-60

Celazole® U-60 is an unfilled PBI polymer suitable for compression molding. U-60 is commonly molded and machined into precision parts for industrial, chemical and petrochemical industries; aerospace; glass making; and liquid crystal display (LCD) panel manufacture.

U-60SD

Celazole® U-60SD is a high purity/ultra-low metal Semiconductor grade PBI thermoplastic recommended for use in Dry Etch Chambers and Sputtering Systems, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). See markets section for more information.

U-60ESD

Celazole® U-60ESD is an electro-static dissipative (ESD) variant of U-60 available as a stock shape or part. U-60ESD incorporates carbon fiber to increase the conductivity of the finished part and is often used where static discharge is a concern.

U-60CF

U-60CF is an ultra-high strength carbon fiber reinforced compression molded PBI variant available as a stock shape.  30% CF reinforced PBI has 36 kpsi tensile strength, 42 kpsi flexural strength, and 65 kpsi compressive strength.

CELAZOLE® U-SERIES PROCESSING: COMPRESSION MOLDING

Celazole® U-60 is an unfilled PBI polymer and comes in fine powder form that is suitable for compression molding to achieve higher strength.
