    摘要: A back-sheet for a photovoltaic module is provided comprising a fire resistant polymeric film and a second polymeric film adhered to the fire resistant polymeric film. The fire resistant polymeric film comprises a polymer that does not melt at temperatures below 275° C. and an inorganic particulate filler selected from inorganic metal oxides and inorganic metal nitrides, and combinations thereof. The fire resistant polymeric film contains from 40 to 75 weight percent inorganic particulate filler based on the total weight of the film, and the fire resistant polymeric film has an average thickness of at least 85 microns. A photovoltaic module comprising such a back-sheet is also provided.

    摘要: A film is disclosed, containing 40-100 weight percent polyimide. The polyimide is derived from a dianhydride component and a diamine component. The dianhydride component is at least 3,3′,4,4′-biphenyl tetracarboxylic dianhydride (BPDA), and optionally is also pyromellitic dianhydride (PMDA) in a mole ratio of 50-100:50-0 (BPDA:PMDA). The diamine component comprises 1,5-naphthalenediamine (1,5-ND) and 1,4-diaminobenzene (PPD) and/or meta phenylene diamine (MPD) in a mole ratio of 15-95:85-5 (1,5-ND:PPD+MPD). The films have exceptional high temperature storage modulus (elastic modulus) and exceptionally low high temperature creep (eplast).
