PBI commercial products

For engineers and researchers searching for materials for specific high temperature applications, data and information about commercially available PBI and PBI blends are important. PBI commercial products include PBI fibers, PBI polymers, compression molded PBI products, melt-processable PBI/PEEK blends, and PBI solutions. Their typical properties are summarized in this section. 

Commercial PBI polymers are in powder form and are golden in color. A moderately low molecular weight fraction PBI is generally used for molding. Higher molecular weight fractions are utilized for solutions, films, coatings and membranes. 

Compression molded PBI stock shapes are commercially available under the trade name Celazole U-60. High temperature and high pressure are needed to compression mold PBI. PBI stock shapes can be further machined into specific parts. With the highest among thermoplastics at about 427°C 

Celazole U-60SD is a special grade of PBI products with extremely low metallic ion contents ( 1 ppm per species) and is generally used in the
