PBI Performance Products


Celazole® PBI (polybenzimidazole) 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. It's; highly suited for use in fluorinated plasmas. Depending upon the application and duration, PBI can withstand temperatures as high as 430°C, and, in short bursts, even up to 760°C. PBI is a thermoplastic polymer with a glass transition temperature (Tg) of 427°C.

The most common grade of Celazole is U-60 (compression-molded, unfilled) which is used in some of the harshest environments - ranging from oil fields to aerospace to semiconductor applications. Celazole® parts perform well when exposed to conditions too severe for most plastics. Celazole U-60 parts outperform Polyimide, PAI and PEEK in many extreme environments.

Celazole U Series Grades- Compression Molding Grades:

  • Celazole U-60 PBI is an unfilled 100% 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; liquid crystal display (LCD) panel manufacture; and photovoltaic (PV) panel manufacture.
  • 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.
  • 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.

    Celazole® T-Series products are PBI alloys designed for Injection Molding and Extrusion.
    Combining the superior mechanical properties and thermal resistance of PBI with the melt process ability of polyaryletherketones (PEEK), these products offer cost-effective high performance.
    Celazole T Series Grades - Injection-Molding & Extrusion Grades:
  • Celazole TU-60 is a high performance unfilled PBI-PEEK blend, ideal for applications requiring no fillers. This material works well for complex geometries and offers the best process ability. Ideal for lamp sockets, connectors and back up seals.
  • Celazole TF-60C is a carbon-reinforced PBI-PEEK blend, ideal for parts that require high strength, very low creep, and deflection resistance. A great match for planetary gears, office equipment, semiconductor, electronic and mechanical applications.
  • Celazole TF-60V is a glass-reinforced PBI-PEEK blend offering thermal and electrical insulation, wear resistance and dimensional stability with the cost efficiency of a direct form process. An excellent choice for high temperature electrical insulators, plasma torch drag cup shields, swirl baffles and parts requiring minimal thermal expansion.
  • Celazole TL-60 is a lube grade PBI-PEEK 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 âÇô particularly under load.
