POLYVINYLIDENE FLUORIDE RESIN COMPOSITION, FILM, BACK SHEET, AND SOLAR CELL MODULE

摘要

Provided are a polyvinylidene fluoride resin composition that has good inorganic pigment dispersivity and that is unlikely to cause a defect due to poor dispersion and has practical mechanical strength characteristics in a film to be formed, and a film, a back sheet, and a solar cell module. Based on 100 parts by mass of a resin component containing two types of polyvinylidene fluorides having different forms or different melt flow characteristics in a total amount of 50 to 95% by mass and polymethyl methacrylate in an amount of 5 to 50% by mass, 7 to 40 parts by mass of a white inorganic pigment and 0.01 to 7 parts by mass of an inorganic pigment for toning are mixed to produce the resin composition. At that time, at least one of the two types of polyvinylidene fluorides to be used has an MFR (230°C, 3.8 kg load) of 3 to 35 g/10 min and the polymethyl methacrylate to be used has an MFR (230°C, 10 kg load) of 2 to 20 g/10 min.
