PBI (Poly Benzoimidazole)
PBI is a material obtained by compression molding of poly benzoimidazole resin and has the highest thermal resistance and mechanical strength among the commercialized plastics. At the same time, it is a clean and highly functional super engineering plastic in which ionic impurities have been minimized.
Applications
Various parts for production line, semiconductor, LCD manufacturing equipment, inspection equipment parts, manufacturing jigs, nuclear power electronic components, precision devices, food, chemicals, welding equipment, plating, metal surface treatment, etc.
