Celazole® (U-Series)  U-60 - PBI Performance Products, Inc. - 

Celazole U-60 PBI is an unfilled 0.6 dL/g inherent viscosity PBI polymer that is most suitable for compression molding. This grade is commonly molded and machined into precision parts for industrial, chemical and petrochemical industries, glass making, as well as chemical synthesis catalyst support systems; it's used in aerospace and other extreme environments.

For these purposes, PBI is offered as a 100-mesh powder direct from PBI Performance Products, Inc.

U-60 grade Celazole® polybenzimidazole (PBI) resin is a unique organic polymer which does not burn in air and has extraordinary high temperature resistance, along with excellent stability to chemicals and hydrolysis.

The data shown here describe an unfilled high-performance part molded of Celazole PBI, with many outstanding properties:
-Highest compressive strength of any unfilled resin
-Excellent tensile and flexural strength
-Good fatigue properties
-Excellent hardness
-Low coefficient of friction
-Outstanding Tg and heat deflection temperature
-Relatively low coefficient of thermal expansion
-High volume resistivity
-Very good plasma resistance

Celazole PBI is ideal for applications where requirements cannot be met by other resins—in extreme high temperatures, in harsh chemical or plasma environments, or in applications where durability and wear resistance are important. Parts molded of Celazole PBI are being used in semiconductor and flat panel display manufacture, electrical insulating parts, heat insulating applications, as well as seals, bearings and wear plates in various industrial applications. They are also being evaluated in demanding aerospace applications requiring outstanding strength and short-term high temperature resistance.
