Vitro Minerals WhiteLite™ 32 Lightweight Mineral Powder
Categories: Ceramic; Oxide

Material Notes: WhiteLite™ Lightweight Mineral Powders are high brightness, synthetic aluminosilicate products for high performance filler and extender applications. With a specific gravity of 2.46, WhiteLite™ engineered powders are 10-17% lighter in weight than traditional naturally mined mineral fillers, which allows greater volumetric extension when used in coatings and plastics. XRD and SEM analyses confirm that the WhiteLite™ aluminosilicate powders are fully amorphous and contain no crystalline silica. Whitelite™ has an index of refraction that offers excellent clarity in clear polymer systems, and contributes to surface toughness in compounded polymers. The chemistry results in relative chemical inertness, making WhiteLite™ resistant to blooming, blistering, or chemical degradation in harsh environments. WhiteLite™ powders enhance a wide range of paints, coatings, plastics, and adhesives. High consistent brightness, tint retention and stain/scrub resistance can be achieved in most paint and coating systems. WhiteLite™ powders have low oil absorption and can be easily dispersed in water- or solvent-based systems. Vitro Minerals’ unique processing system and true particle size classification provides consistent product quality for 2 grades (WL-32, WL-42) with finenesses covering a range of potential applications. Under a microscope, WhiteLite™ particles are transparent, angular-shaped particles with similar dimensions in the x, y and z axis.
