Lithopone, a pigment composed of zinc sulfide and barium sulfate, is prized for its ability to offer excellent hiding power and brightness. In China, the production process of lithopone is meticulously controlled, ensuring that each batch meets stringent quality standards. This dedication to precision not only enhances the performance of end products but also elevates China's reputation in the global market.

Looking ahead, the future of pigment lithopone factories appears promising. With ongoing research into cleaner production methods and the development of new applications for lithopone, these facilities are poised to remain relevant in the pigment industry. Additionally, rising awareness about sustainable practices may drive further innovation within these factories, solidifying their position as leaders in responsible pigment production.

Application:
1. Due to its rheological and optical properties, Lithopone offers technical and economic advantages wherever organic and inorganic resin systems need to be relatively highly pigmented for specific applications. Lithopone has therefore traditionally been used in putties, mastics, jointing and sealing compounds, primers, undercoats and marking paints. In powder coatings it is possible to replace TiO2 partially, very economically.
2. The low Mohs' hardness of Lithopone leads to low abrasiveness in comparison with TiO2.
3. Lithopone 30 % (= 30% zinc sulfide share) is proven to be of particular use as a TiO2 Substitute in thermoplastic masterbatches. Even at very high pigment loadings it disperses easily. A masterbatch containing 50 % TiO2 and 25 % Lithopone 30 % DS has the same hiding power as one containing 60 %TiO2. Cost savings are strongly related to the price ratio of Lithopone and TiO2 and the price of for example polyethylene or polypropylene.
4. The Lithopone batch has a much higher extrusion rate too. Furthermore the impact strength of many thermoplastics such as PP and ABS can be noticeably improved by using Lithopone as a TiO2 substitute. Generally spoken, Lithopone can be used at loadings up to 80 % by weight without causing polymer breakdown
