UPI (Ultra-high-performance polyimide)<\/strong><\/span><\/h2>\n

 <\/p>\n

\"\"<\/p>\n

Aromatic polyimides are used on a wide range of fields: aerospace, automobile, electronic application, because of its extraordinary properties, e.g., good mechanical properties, great heat resistance, electric insulation, and solvent resistance.<\/p>\n

8000 series is a stock shape molded from biphenyltetracarboxylic dianhydride (BPDA) base polyimide: UIP-SA which is synthesized in UBE.<\/p>\n

This polyimide shows ultra high heat resistance and low water absorption. Especially, its heat deflection temperature is around 480\u00b0C which is the highest level value of all plastics.<\/p>\n
