white titanium dioxide suppliers

Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.

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
