Product Description
Description:Polyamide acid solution is cast into film and stretched, and then amidated at high temperature. The film is yellow and transparent, with a relative density of 1.39 ~ 1.45. It has outstanding properties on high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation. It can be used in the air at 250 ~ 280 ºC for a long time. The glass transition temperature is 280 ºC (upilex R), 385 ºC (Kapton) and above 500 ºC (upilex s). The tensile strength is 200MPa at 20 ºC and more than 100MPa at 200 ºC. It is especially suitable for flexible printed circuit board substrate and various high temperature resistant electrical insulation materials.Technical Data Sheet
