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.
