Le lithopone, blanc de lithopone ou blanc de Comines est un pigment blanc composé d'un mélange de sulfure de zinc et de sulfate de baryum, généralement en proportions équimolaires.
We apply titanium dioxide to our skin through sunscreens, makeup, lip balms, nail polish, and other cosmetic products.
The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.
TiO2 possesses different qualities depending on whether it is produced as a pigment or a nanomaterial. Both forms are tasteless, odourless and insoluble.
Lithopone 30% increases extruder performance and reduces processing costs, improves quality and is suitable for masterbatch for injection of Polyolefins, ABS, Polycarbonate, Polypropylene, Polyethylene, Polystyrene, single layer films, multi-layer films and for white, coloured and filled masterbatch. The combination of Lithopone 30 with TiO2 results in improved mechanical properties including higher elongation values and better impact resistance.
