PORTARYTE B15 is a micronized natural baryte filler derived from carefully selected, ultra-white natural baryte. It features excellent chemical inertness and low levels of impurities, including transition and heavy metals. Its low quartz content ensures low abrasiveness and minimizes health risks during handling. PORTARYTE B15 is used across a wide range of applications due to these characteristics. It serves as a natural alternative to fine synthetic Blanc Fixe in high-gloss formulations. This filler is especially suitable for applications requiring chemical inertness and minimal impurities. Its fine particle size and density make it ideal for products where durability, longevity, and aesthetic quality are critical.
