UPI (Ultra-high-performance polyimide)
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.
8000 series is a stock shape molded from biphenyltetracarboxylic dianhydride (BPDA) base polyimide: UIP-SA which is synthesized in UBE.
This polyimide shows ultra high heat resistance and low water absorption. Especially, its heat deflection temperature is around 480°C which is the highest level value of all plastics.
