Celazole® PolyBenzImidazole (PBI) is the best performing engineering thermoplastic. Among the unfilled thermoplastics, Celazole offers highest temperature resistance and best mechanical property retention above 4000F/2060C. It offers excellent wear resistance and load carrying capacity at very high temperatures. Highly pure ionic structure makes it suitable for semiconductor manufactures for vacuum chamber applications. Because it doesn’t stick to other melting plastics, Celazole is a good choice for contact seals and insulator bushings. Celazole offers excellent ultraviolet transparency and exceptional thermal and chemical stability.
