Title:
VINYLIDENE FLUORIDE POLYMER COMPOSITION, POLYMER FILM, LAYERED BODY, AND BACK SHEET FOR SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2016/143549
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a vinylidene fluoride polymer composition containing a large quantity of titanium oxide for enhancing concealing properties and having excellent heat resistance properties such as thermal durability, the vinylidene fluoride polymer composition being suitable for application in a film such as a back sheet for a solar cell module; and a vinylidene fluoride polymer film or the like. The vinylidene fluoride polymer composition provided by the present invention contains 15-100 parts by mass of titanium oxide with respect to 100 parts by mass of a vinylidene fluoride polymer, and contains 0.01-10 parts by mass of a phosphite-based stabilizer with respect to a combined total of 100 parts by mass of the vinylidene fluoride polymer and the titanium oxide. The present invention furthermore provides a vinylidene fluoride polymer film formed from the composition, a layered body provided with a layer comprising the film, and a back sheet for a solar cell module.
