PORTARYTE D80 is a micronized natural off-white baryte filler that offers excellent chemical inertness and low binder absorption. With a mean particle size of 13 µm, PORTARYTE D80 is ideal for applications where high brightness and consistent color are not critical. Its exceptionally high density of 4.4 g/cm³ makes it an economical choice for sound-deadening and mass-loading applications. Produced from carefully selected, naturally occurring off-white baryte, PORTARYTE D80 is manufactured under strict quality control standards. Its chemical composition and particle size distribution are closely monitored to ensure consistent performance. PORTARYTE D80 is well-suited for use in applications requiring durability and long-term stability, without placing primary emphasis on visual appearance.
