Products:
Including the average benzene polyimide film and biphenyl polyimide film two categories. The former is the DuPont trade name Kapton from pyromellitic dianhydride with ether diamine obtained. The latter produced by Japan's Ube Kosan, trade name Upilex, biphenyl dianhydride with ether diamine (R type) or the phenylenediamine (S type) was obtained. The thin film manufacturing method: polyamic acid soluble liquid flow cast film after stretching, heat imidization. The film was transparent yellow, the relative density of 1.39 ~ 1.45.
Product features:
Temperature class: H (180 ° C)
Other features: prominent high temperature, radiation-resistant, chemical resistant and electrical insulation properties, can be used at 250 to 280 ° C air for a long. The glass transition temperatures were 280 ° C (Upilex R of), 385 ° C (Kapton) and 500 ° C or above (Upilex S). 20 ° C when the tensile strength of 200 MPa, 200 ° C greater than 100 MPa.
Product Application: Especially suitable for flexible printed circuit board substrate and a variety of high temperature motor electrical insulation materials
