Opacifiers / Hiding Agents

Based on 11 products - Last update on the Jul 1, 2025

Opacifiers or hiding agents, are typically presented as fine powders or dispersions, often white or off-white in color. Key features include high opacity, high refractive index, excellent hiding power, and chemical stability. Used in the plastics industry where their ability to conceal underlying substrates or impart a desired level of translucency is crucial for both aesthetic and functional purposes. 

Alternatives to traditional opacifiers include transparent fillers and matting agents. Sub-types include titanium dioxide (TiO2), zinc oxide (ZnO), and calcium carbonate (CaCO3).

Opacity Pigment™ FP-550

by FP-Pigments

Opacity Pigment™ FP-550 by FP-Pigments acts as an opacifier. It can easily be incorporated in polyolefin masterbatches using normal premix and extrusion operations. It is suitable for plastics and end applications including blown films and injection molding. The unique engineered structure improves the efficiency of existing titanium dioxide pigments and enhances their performance, allowing the formulator to optimize the product performance and reduce raw material costs. <br> <ul style="padding-left: 40px;"><li>It is designed to provide optimal optical properties enabling partial replacement of TiO<sub>2</sub> depending upon the dilution and film thickness of the end use product. </li> <li>The recommended replacement level is between 10-15%.</li> <li>It maintains opacity & film quality and provides high brightness & low yellowness.</li> <li>Its lower tinting strength provides advantage in colored plastics where chroma and hue can be maintained at lower colored pigment addition levels. </li> <li>Opacity Pigment™ FP-550 is fully REACH compliant and approved from FDA & JHOSPA ([B]NJ-36699). </li></ul>
