Material Notes:
Description: UPILEX, the ultra-high heat-resistant polyimide film, is the product of the polycondensation reaction between biphenyltetracarboxylic dianhydride (BPDA), of which process Ube Industries originally developed, and diamine. Most notable of these characteristics is UPILEX's physical, mechanical, electrical, and chemical properties under high-temperature conditions.UPILEX-S demonstrates outstanding mechanical characteristics through a wide temperature range. UPILEX-S displays high tensile strength and modulus, and also features outstanding long-term heat resistance. Another advantage inherent in UPILEX-S is its high resistance to hydrolysis, as its properties are practically unaffected, even by immersion in boiling water for long periods of time.Information provided by UBE.
