HEAT-RAY-BLOCKING FLUORORESIN FILM

摘要

A heat-ray-blocking fluororesin film comprising a heat-ray-blocking metal oxide and a hydrotalcite-type compound represented by general formula [chemical formula 1], wherein the content of the hydrotalcite-type compound is 0.03 to 1.0 wt%. Provided is a heat-ray-blocking fluororesin which can exhibit excellent heat-ray-blocking performance while keeping the properties inherent in fluororesin films, such as mechanical properties, transparency and long-term weather resistance, and which is transparent and can be used out of doors for a long period of time. Mg2+ 1-a·Al3+ a(OH-)2·ANn- a/n·cH2O (wherein 0.2 ≤ a ≤ 0.35 and 0 ≤ c ≤ 1 and ANn- represents an anion having a valency of n).
