Fire resistant back-sheet for photovoltaic module |
| 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. |

1. A back-sheet for a photovoltaic module comprising:
a fire resistant polymeric film comprising a polymer that does not melt at temperatures below 300° C. and an inorganic particulate filler selected from inorganic metal oxides and inorganic metal nitrides, and combinations thereof, wherein said fire resistant polymeric film contains from 40 to 75 weight percent inorganic particulate filler based on the total weight of the film, and wherein said fire resistant polymeric film has an average thickness of at least 90 microns; and a second polymeric film adhered to said fire resistant polymeric film, said second polymeric film being a fluoropolymer film. |
