  • Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.  

  • Titanium dioxide is a widely used substance in the cosmetic industry, especially in China. It is a naturally occurring mineral that is used as a whitening and opacifying agent in many cosmetics, such as sunscreen, foundation, and face powder.
  • China, the world's most populous nation and a global economic powerhouse, has emerged as a dominant player in the production of titanium dioxide (TiO2), a critical pigment used in a myriad of industries from paint and plastics to cosmetics and food. The country's billion-ton TiO2 industry is not just a testament to its manufacturing prowess but also a reflection of its strategic approach towards resource optimization and market dominance.

  • Polyvinyl Butyral Resin (PVB) is a solvent Resin synthesized by the acetal reaction of Polyvinyl Alcohol (PVA) and butyraldehyde in contact with coal.

    Because Pvb Resin itself contains a lot of hydroxyl groups, it can bridge with some thermosetting resins to improve the properties of chemicals and film hardness.

    Because PVB resin has the above excellent characteristics, it is widely used in adhesive safety glass intermediate film of automobile and building, rust cutting primer, baking paint, wood paint, printing ink, adhesive of electronic ceramics and printed circuit board, adhesive between metal and metal, between metal and plastic, modifier of hot-melt adhesive, iron dimension waterproof processing of textile, etc. A variety of new industrial applications are also continuously developed and applied.

    The general characteristics of PVB are as follows:

    The appearance of polyvinyl butyral (PVB) resin is white spherical porous particles or powder, and its specific gravity is 1:1; However, the filling density is only 0.20 ~ 0.35g/ml.

    Thermal properties

    The glass transfer temperature (TG) of polyvinyl butyral (PVB) resin ranges from 50 ℃ of low degree of recombination to 90 ℃ of high degree of recombination; The glass transfer temperature can also be adjusted by adding an appropriate amount of Plasticizer to reduce it below 10 ℃.

    Mechanical properties

    The coating of polyvinyl butyral (PVB) resin has good water resistance, water resistance and oil resistance (it is resistant to aliphatic, mineral, animal and vegetable oils, but not to sesame oil). PVB is widely used in printing inks and coatings because it contains high hydroxyl groups and has good dispersibility to pigments.

    In addition, its chemical structure contains both hydrophobic acetal and acetic ACID groups and hydrophilic hydroxyl groups, so PVB has good adhesion to glass, metal, plastic, leather and wood.

    Chemical reaction

    Any chemical that can react with secondary alcohol will also react with PVB. Therefore, in many applications of PVB, it is often used with thermosetting resin to bridge and harden with the hydroxyl group of PVB, so as to achieve the characteristics of chemical resistance, solvent resistance and water resistance.

    Of course, films with different characteristics (such as hardness, toughness, impact resistance, etc.) can be prepared according to different types of thermosetting resin and different mixing ratio with PVB.

  • The inception and evolution of lithopone can be traced back through various industries and diverse applications. Revered for its robust hiding power, this white pigment, also called sulfide of zinc white, has been an invaluable asset to industries requiring a durable and reliable white pigment. Lithopone was an economical and functional solution as an alternative to lead carbonate, which is prone to change, and zinc oxide, known for its brittleness.

  • When selecting a supplier for titanium dioxide anatase B101, factors such as product purity, particle size distribution, and batch-to-batch consistency are critical considerations
  • After settling, the clear solution containing the titanium oxide, is run oil andfurther processed, whereby a roduct is obtained containing approximate y 35 per cent titanium oxide, 2 per cent sulphuric acid and 63 per cent of water. This product is known in the trade as titanium acid cake. It is a plastic mags having somewhat the consistency of mu 1 ljha've discovered that lithopone can be greatly improved by the suitable use of this titanium acid cake, and that the results obtained are dependent to a large extent upon the methods'by which this titanium acid cake is used,'in the production of lithopone.

With the continued growth of the market for titanium dioxide, these factories will continue to be at the forefront of innovation and production in the field of white pigments.

  • China’s government is working on its plan to eliminate outmoded capacities of TiO2 and strengthen environmental protection measurements. Small and middle-sized enterprises, with a production capacity under 50,000t/a, are the ones to suffer. They mostly get merged or need to withdraw from the market. Without their production capacity of about 500,000 tonnes yearly, the domestic output might shrink about 20%. This will enhance the power of listed companies in China immensely, which is one of the main reasons for the effort to go public.

  • In addition to offering bulk quantities of silver titanium dioxide, these suppliers often offer custom formulation services. This allows customers to tailor the compound's properties according to their specific applications, whether it's adjusting the particle size for better dispersion in plastics or enhancing the antimicrobial efficacy for use in medical devices.
