  • Secondly, TiO2 acts as a UV stabilizer in plastics. When exposed to sunlight, plastics can degrade over time due to the harmful effects of ultraviolet rays. However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic material However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic material However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic material However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic materialtio2 used in plastic manufacturers. This property extends the lifespan of plastic products and reduces the need for frequent replacements, making it an eco-friendly option for manufacturers.

  • TR 92 titanium dioxide is known for its exceptional whiteness, which is important for achieving vibrant and long-lasting colors in paints and coatings. Its high opacity ensures excellent coverage, allowing for fewer coats and reducing overall costs. Additionally, TR 92 titanium dioxide is resistant to fading and degradation from UV exposure, making it suitable for outdoor applications.
  • Furthermore, titanium dioxide is used in various consumer products, such as cosmetics, toothpaste, and sunscreen, for its whitening and UV-blocking properties. The pigment is added to these products to provide a bright and flawless appearance while also protecting the skin from the harmful effects of UV radiation. Titanium dioxide is considered safe for use in cosmetics and personal care products, as it is non-toxic and non-irritating to the skin.

  •  

  • In Home Care products, the presence of titanium dioxide is declared in line with local regulations, which can vary across the world. In some countries, titanium dioxide is not declared if only a small amount of the ingredient is used. In other countries titanium dioxide is grouped under ‘colourants’ in the ingredients list. In Europe, regulation requires all home care ingredients to be disclosed through a supporting website. You can find our product ingredient information page by visiting ‘

  • Overall, the use of lithopone is crucial in various industries due to its outstanding properties and performance. It is an essential ingredient in paint, rubber, plastic, ceramics, and cosmetics, where it enhances the quality and appearance of the final products. Suppliers play a vital role in providing high-quality lithopone to manufacturers, ensuring the consistent performance of this versatile pigment.

  • There is some concern regarding skin and intestinal absorption of titanium dioxide nanoparticles, which are less than 100 nm in diameter.

  •  

  • Yes. According to the FDA and other regulatory agencies globally, “titanium dioxide may be safely used for coloring foods”. Titanium dioxide is safe to use, and the FDA provides strict guidance on how much can be used in food. The amount of food-grade titanium dioxide that is used is extremely small; the FDA has set a limit of 1 percent titanium dioxide for food. There is currently no indication of a health risk at this level of exposure through the diet.

  • In addition to these factors, global economic conditions and trade policies can also affect the anatase price. Fluctuations in currency exchange rates and changes in import/export duties can make anatase more or less expensive for different countries. For example, if a country imposes high tariffs on imported anatase, it may encourage local production but could also increase the cost for consumers within that country.

  • Titanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent. In lotions and creams (dermal exposure), it is not a risk for adverse health effects. However, when titanium dioxide is inhalable—as it may be when in powder form—it is considered a possible carcinogen by the International Agency for Research on Cancer.Titanium dioxide nanoparticles do not appear to confer any unique health hazards.

  • In conclusion, titanium dioxide plays a crucial role in the plastic manufacturing industry due to its unique properties as a white pigment, UV stabilizer, and mechanical property enhancer. Its use not only improves the quality and performance of plastic products but also contributes to sustainable practices by extending their lifespan and reducing waste. As technology continues to advance, it is likely that TiO2 will remain a vital ingredient in the production of high-quality plastics for years to come.

  • Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie. En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.

O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

  • Free Sample TiO2 DongFang R5566 Titanium Dioxide

  • The demand for titanium dioxide has been steadily increasing over the years, driven by the growing demand for paints, coatings, plastics, and other products that require this versatile compound. As a result, the titanium dioxide manufacturing industry has been expanding rapidly, with many companies investing in new production facilities and technologies to meet the growing demand.
  • Uses and benefits

  • Why does the exposure route matter, and what's the risk? 

  •  

  • Titanium dioxide can boost and brighten colors because of how well it absorbs and also scatters light. In food and drugs, this additive is known as E171 and helps define colors clearly and can prevent degradation (cracking and breakdown of materials) from exposure to sunlight.
