While lithopone and anatase titanium white gained traction between the 1920s and 1950s, by the advent of the First World War, rutile titanium white had started to overshadow them. Their significance in the artist’s palette has since dwindled, and their use as an artist’s pigment is currently nearly obsolete.

lithopone supplier 30% increases extruder performance and reduces processing costs, improves quality and is suitable for masterbatch for injection of Polyolefins, ABS, Polycarbonate, Polypropylene, Polyethylene, Polystyrene, single layer films, multi-layer films and for white, coloured and filled masterbatch. The combination of lithopone supplier 30 with TiO2 results in improved mechanical properties including higher elongation values and better impact resistance.
