Understanding Lithopone Suppliers and Applications

Lithopone is a white pigment made from a mixture of zinc sulfide (ZnS) and barium sulfate (BaSO4). It has gained significant recognition in various industries due to its excellent properties, including high opacity, durability, and resistance to chemicals. Typically referred to by its chemical formula, Lithopone provides a versatile solution for those seeking a high-quality pigment for their products.

Composition and Characteristics

Lithopone is primarily composed of around 28-30% zinc sulfide and barium sulfate, exhibiting a unique combination of qualities that make it stand out among other pigments. The presence of both components enhances its performance, allowing it to achieve remarkable whiteness and cover both bright and transparent surfaces effectively.

One distinctive feature of Lithopone is its outstanding durability. This makes it an ideal choice for outdoor applications, where exposure to harsh environmental conditions is a concern. Furthermore, Lithopone demonstrates excellent resistance to fading, making it a preferred option for paints, coatings, and plastics that require long-lasting brightness.

Applications of Lithopone

Lithopone is widely used in various industries, including paints and coatings, plastics, rubber, and even cosmetics. In the paint industry, it serves as a cost-effective alternative to titanium dioxide, providing similar performance at a lower price. Its ability to enhance opacity and brightness in paint formulations makes it popular among manufacturers looking to maintain quality while staying within budget constraints.

In plastics, Lithopone is utilized as a filler and white pigment to improve the aesthetics and add functional properties to plastic products. It enhances the whiteness and opacity of polypropylene, polyethylene, and polystyrene, making it a valuable additive in packaging materials and consumer goods.

Additionally, Lithopone finds usage in the rubber industry, particularly in the production of tires and other rubber products. The pigment not only contributes to the visual quality of these products but also aids in improving resistance to ultraviolet (UV) light, thereby extending the lifespan of rubber items.

In the cosmetic sector, Lithopone is often used in formulations for sunscreen and makeup products due to its sun-blocking properties. Its non-toxic and safe profile makes it suitable for use on the skin, providing both aesthetic appeal and protective benefits.
