The Allure of Real Silver Mirrors
Environmental Impact
This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature and quenched in cold water. The second heating in a muffle furnace at 725 °C produces crystals of the right optical size.
Understanding Titanium Dioxide
Key benefits for stakeholders
Lithopone is added to plastic resin systems to enhance UV protection of the final plastic products that includes outdoor plastics and automotive plastics. It is used as a white pigment for plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon, and polyoxymethylene (POM). It ensures that UV rays do not penetrate and damage the product and its appearance.
Because of its ability to absorb UV light, it's particularly useful as an ingredient in sunscreens — while its light-scattering properties are great for applications that require white opacity and brightness, such as in paint and paper.
