Aluminosilicate compositions as partial replacement for titanium dioxide in pigmented polyvinyl chloride and polyvinyl chloride type compositions |
摘要 |
Disclosed are polyvinyl chloride and polyvinyl chloride type compositions using a titanium dioxide based whitening/opacifying package containing up to about 30 percent by weight of an aluminosilicate composition. In the whitening/opacifying package the aluminosilicate composition acts as a replacement for the same amount by weight of titanium dioxide. The whitening/opacifying package achieves a measure of overall appearance (DE* value), a Yellowness Index, and a percentage of light transmitted (opacity) which are substantially comparable or superior to those achieved by the same weight of pure titanium dioxide.
