Abstract:
A purpose of the present invention is to provide a non-combustible film which has excellent flexibility, excellent moisture resistance and high mechanical strength. Another purpose of the present invention is to provide: a dispersion liquid for non-combustible films, which is used for the production of the non-combustible film; a method for producing a non-combustible film, which uses the dispersion liquid for non-combustible films; and a solar cell back sheet and a flexible board, each of which uses the non-combustible film. Another purpose of the present invention is to provide a solar cell which uses the solar cell back sheet. The present invention is a non-combustible film, which contains a water-insoluble inorganic compound and a heat-resistant synthetic resin, and wherein the content of the water-insoluble inorganic compound is 30-90% by weight (inclusive) relative to the total weight of the non-combustible film. The non-combustible film belongs to combustibility class VTM-0 as determined by a VTM test in accordance with UL-94 standard.
