  • In this article, we will delve into the fundamentals of rutile, its applications, and the key players in the rutile market factory industry. We will also discuss the current trends and future prospects of this rapidly evolving market.

  • In a study published in the journal Food and Chemical Toxicology in 2016, researchers investigated whether titanium dioxide exposure led to an increase in colorectal tumor creation in mice by using a colitis associated cancer model. By measuring tumor progression markers, the researchers found that mice given titanium dioxide experienced enhanced tumor formation in the distal colon.  There was also a decrease of cells that act as a protective barrier in the colon. The researchers wrote: “These results suggest that E171 could worsen pre-existent intestinal diseases.”

  • China, with its abundant raw material resources and advanced manufacturing capabilities, has emerged as a major lithopone pigment manufacturer, catering to both domestic and international markets. Other countries, such as India and the United States, also contribute significantly to the global supply chain, ensuring a steady flow of this vital pigment.

  • A steep decline in the prices of titanium dioxide was observed in the second half of 2022 as the erratic energy costs along with rising covid cases affected the market negatively. In addition to this, the decreased offtakes from paints and coating industries, weak economic growth, and strict restrictions imposed to deal with the resurgence of covid cases further aided the declining trajectory of titanium butoxide prices.

  • Anatase titanium dioxide is also known for its excellent color stability and retention properties. When exposed to light, heat, and other environmental factors, the pigment maintains its vibrant color and does not fade or degrade easily. This makes it an ideal choice for exterior paints and coatings that are exposed to harsh weather conditions.
  • Titanium dioxide, also known as TiO2, is a white inorganic compound that has a wide range of applications in various industries. One of the most significant uses of titanium dioxide is as a pigment in paints, plastics, and paper. The price per kilogram of titanium dioxide varies depending on several factors, including the quality, purity, and production method.

  • Application of lithopone in rubber and plastics application of lithopone in plastics and pigments lithopone can whiten and improve the compressive strength of products. Lithopone is easy to disperse rapidly, and thus the production process of this product is convenient, especially the molding, injection molding and actual operation process. It is worth mentioning that, with its organic chemical plasticity, it can also be integrated into the vulcanized rubber effect of recycled rubber.



  • Pure PVB is non-toxic and harmless to human body. In addition, ethyl acetate or alcohol can be used as solvent, so PVB is widely used in printing ink of food containers and plastic packaging in European and American countries.

    Storage safety properties

    PVB can be stored for two years without affecting its quality as long as it is not in direct contact with water; PVB shall be stored in a dry and cool place and avoid direct sunlight. Heavy pressure shall be avoided during PVB storage.

    Solubility

    PVB is soluble in alcohol, ketone, ester and other solvents. The solubility of various solvents changes according to the functional group composition of PVB itself. Generally speaking, alcohol solvents are soluble, but methanol is more insoluble for those with high acetal groups; The higher the acetal group, the easier it is to dissolve in ketone solvents and ester solvents;

    PVB is easily soluble in cellosolve solvents; PVB is only partially dissolved in aromatic solvents such as xylene and toluene; PVB is insoluble in hydrocarbon solvents.

    Viscosity characteristics of PVB solution

    The viscosity of PVB solution is greatly affected by the formula of solvent and the type of solvent; Generally speaking, if alcohol is used as solvent, the higher the molecular weight of alcohol, the higher the viscosity of PVB solution;

    Aromatic solvents such as xylene and toluene and hydrocarbon solvents can be used as diluents to reduce the viscosity of PVB solution; The effect of PVB chemical composition on viscosity is summarized as follows: under the same solvent and the same content of each base, the higher the degree of polymerization, the higher the solution viscosity; Under the same solvent and the same degree of polymerization, the higher the acetal group or acetate group, the lower the solution viscosity.

    Dissolution method of PVB

    Where mixed solvents are used, the dissolution step is to first put aromatic solvents (such as xylene, toluene, etc.) or ester solvents (such as n-butyl acetate, ethyl acetate, etc.) into the mixing, slowly put PVB into the mixing, and then add alcohol solvents (such as n-butanol, ethanol, etc.) after PVB is dispersed and expanded,

    At this time, the dissolution time can be shortened by heating; Using this dissolution method, the formation of lumpy PVB can be avoided (because the dissolution time will be several times after the formation of lumpy PVB), so the dissolution speed can be accelerated. Generally, the ratio of aromatic and alcohol solvents is 60 / 40 ~ 40 / 60 (weight ratio), and PVB solution with low viscosity can be prepared.

    The solvent composition contains 2 ~ 3wt% water, which can improve the hydrogen bonding strength of alcohol solvents and help the solubility of PVB.

    Processing properties

    Although PVB resin is a thermoplastic, it has little processability before plasticizer is added. Once plasticizer is added, its processability is very easy.

    The purpose of general coatings and adhesives is to change the resin characteristics by adding plasticizers to meet the application requirements, such as film softness, reducing the TG point of the resin, reducing the heat sealing temperature, maintaining low-temperature softness, etc.

    Compatibility

    PVB can be compatible with a variety of resins, such as phenolic resin, epoxy resin, alkyd resin and     MELAMINE resin.

    B-08sy, b-06sy and b-05sy with high acetal degree can be mixed with nitrocellulose in any proportion. PVB and alkyd resin are partially compatible. General PVB is compatible with low molecular weight epoxy resin, while high molecular weight epoxy resin needs PVB with high acetal degree to be compatible with each other.

  • Titanium dioxide can amplify and brighten white opacity because of its exceptional light-scattering properties. In food and drugs, these properties help to define colors clearly and can prevent products from UV degradation.

  • Titanium dioxide, also known as TiO2, is a versatile and widely used white pigment in various industries. As a key ingredient in paints, coatings, plastics, and even food and pharmaceutical products, titanium dioxide plays a crucial role in enhancing the appearance and performance of these products. With its excellent brightness, opacity, and UV-resistant properties, titanium dioxide is the go-to choice for manufacturers looking to achieve high-quality results.

  • Titanium dioxide is the most widely used whitening pigment in the world and has been linked to adverse health effects, particularly genotoxicity and intestinal inflammation. It is applied as food coloring and a whitening agent to a wide variety of foods, including chewing gum, cakes, candies, breads and ice cream. 

  • In the realm of pigments, titanium dioxide's ability to reflect light across the visible spectrum makes it an ideal candidate for brightening products. It is widely used in paints, plastics, paper, inks, food coloring, and cosmetics. The addition of TiO2 not only enhances the whiteness but also improves the durability and opacity of these materials. Moreover, its non-toxic nature ensures that it can be safely used in products that come into direct contact with humans, such as food colorants and cosmetics.

  • Though the regulated use of titanium dioxide in food products is legal in the U.S. and Canada, it's banned in some other countries, notably throughout Europe. In May 2021, the European Food Safety Authority announced that titanium dioxide can no longer be considered safe as a food additive.

  • Some consumer advocacy groups and health agencies — particularly, those at the Environmental Working Group — have been pushing federal officers at the Food and Drug Administration (FDA) to reconsider their existing rules on the additive, which is commonly found in processed snacks and sweets.
