POLYVINYLIDENE FLUORIDE RESIN COMPOSITION, COLORED RESIN FILM, AND BACKSHEET FOR SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a polyvinylidene fluoride (PVDF) resin composition which improves the heat resistance of PVDF resin, and is suppressed in thermal decomposition and thermal discoloration even when a large amount of colorant is contained in the PVDF resin.

SOLUTION: A backsheet for a solar cell module includes: the PVDF resin composition containing 0.5-70 pts.wt of talc as a thermal stabilizer, more preferably 2-60 pts.wt of the colorant and 2-60 pts.wt of the talc (colorant:talc=20:1-1:20), based on 100 pts.wt of the PVDF resin; a colored resin film formed of the PVDF resin composition; and a layer consisting of the colored resin film.
