PORTARYTE B45

PORTARYTE B45 is a micronized natural baryte filler produced from carefully selected, very white, naturally occurring baryte. It features a D50 particle size of 9.0 µm and an oil absorption of 11 g/100 g. With excellent chemical inertness and extremely low levels of impurities—including transition and heavy metals—it is ideal for applications requiring high durability and long-term stability. Thanks to its low abrasiveness and absence of health-related concerns, PORTARYTE B45 is widely used as a natural alternative to fine synthetic Blanc Fixe in high-gloss applications. Its standardized quality and consistent physical properties, such as density, bulk density, and hardness, make it particularly suitable for industries where both aesthetics and long-lasting performance are critical.
