Abstract
A polyvinylidene fluoride resin composition containing a polyvinylidene fluoride resin and titanium oxide, wherein the content of the titanium oxide is 5 to 100 parts by weight per 100 parts by weight of the polyvinylidene fluoride resin, the resin composition contains, as a heat stabilizer, at least one compound selected from the group consisting of calcium polyhydroxymonocarboxylates, calcium salts of aliphatic carboxylic acids having 5 to 30 carbon atoms, calcium carbonate, calcium hydroxide, zinc oxide and magnesium oxide in a proportion of 0.1 to 20 parts by weight, and a weight ratio of the titanium oxide to the heat stabilizer is 100:1 to 3:1.
