CALCIUM SULFATE AS A PARTIAL REPLACEMENT FOR TITANIUM DIOXIDE IN WHITE COMPOUNDS |
摘要 |
The invention relates to a whitened polymeric blend composition in which the whiteness is achieved by the substitution of from about 0 to about 20 parts per hundred rubber of calcium sulfate for from about 0 to about 20 parts per hundred rubber of titanium dioxide by volume. The invention allows for a reduction of up to 20 percent of the titanium dioxide, while maintaining a brightness of at least 85 as measured on the L scale of the Minolta Chroma Meter test.
