PBI Performance Products Celazole® PBI U-60 Unfilled Polybenzimidazole Resin
Categories:	Polymer; Thermoplastic; Polybenzimidazole (PBI)
Material Notes:	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-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 tochemicals and hydrolysis. Features include: 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 Information provided by PBI Performance Products
