What Is Lithopone and Why Is It Still Relevant Today?

In the world of pigments and industrial fillers, Lithopone has been around for over a century. But what exactly is it, and why do manufacturers still choose it over newer alternatives?

What Is Lithopone?

Lithopone is a white pigment composed mainly of barium sulfate (BaSO₄) and zinc sulfide (ZnS). It was first developed as a safer alternative to lead-based pigments and has since found a wide range of applications across industries.

Where Is Lithopone Powder Used?

One of the most common forms is Lithopone powder, known for its brilliant whiteness, good hiding power, and excellent weather resistance. It's widely used in:

• Paints and coatings

• Plastics and rubber

• Paper manufacturing

• Linoleum flooring

• Printing inks

Its inertness and non-toxic properties make it especially valuable in consumer goods and construction materials.

What Is the CAS Number of Lithopone?

If you're dealing with chemical specifications, you might know Lithopone powder CAS1345-05-7. This identifier is commonly used in industry to standardize chemical procurement, quality control, and regulatory compliance.

Why Choose Lithopone Over Other White Pigments?

Despite the availability of titanium dioxide and other modern pigments, Lithopone remains relevant for several reasons:

• Cost-effectiveness: It's a more economical option in many formulations.

• Stable performance: Lithopone offers good dispersion, weather resistance, and chemical stability.

• Complementary properties: It is often blended with titanium dioxide to improve performance and reduce cost.

Whether you're a manufacturer looking for an affordable pigment or a formulator seeking balanced performance in coatings and plastics, Lithopone remains a valuable choice. From traditional uses to modern blends, the enduring relevance of Lithopone powder—including Lithopone powder CAS1345-05-7—is a testament to its versatility and reliability.
