  • 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.

  • Overall, buff percentage is a critical factor that manufacturers of titanium dioxide must carefully manage to ensure the quality, consistency, and cost-effectiveness of their products. By investing in advanced technology and processes to control buff percentage, manufacturers can meet the specific requirements of their customers and maintain a competitive edge in the market. As the demand for titanium dioxide continues to grow across various industries, manufacturers must continue to innovate and improve their processes to meet the evolving needs of their customers.

  • Cosmetic grade titanium dioxide is considered safe for use in cosmetics, as it is a non-toxic and non-irritating substance. It is often used to provide a smooth and even finish to cosmetics, as well as to protect the skin from the sun's harmful UV rays.
  • Mexican researchers sought to evaluate the effects of E171 across a span of conditions in mice, including its influence on behavior, along with the effects on the colon and liver. The research, published in 2020 in the journal Food and Chemical Toxicology, showed that E171 promoted anxiety and induced adenomas, or noncancerous tumors, in the colon. They also found that E171 heightened goblet cells hypertrophy and hyperplasia, which is typically seen in asthma patients and triggered by smoking or external pollutants and toxins. They also noted mucins overexpression in the mice, which can be linked to cancer cell formation. 

  • Thanks to its rheological and optical properties, Lithopone 30% offers both technical and economic advantages in the substitution of titanium dioxide in different applications. Among these advantages, it has been observed that Lithopone 30% has algaecidal properties in paints, which gives greater protection to the coating. 

  • One of the key factors contributing to the popularity of R996 TiO2 among paint factories is its environmental sustainabilityr996 tio2 lomon china titanium dioxide for paint industry factories. Lomon China emphasizes eco-friendly production processes, reducing the environmental impact while maintaining product efficacy. This commitment to sustainability aligns with the growing global trend towards green manufacturing practices.
  • In conclusion, antioxidants are a powerful tool in the fight against disease and cellular damage. By incorporating them into your diet through whole foods or supplements, you can support your overall health and well-being. So next time you reach for a piece of fruit or a handful of nuts, remember that you are not only satisfying your hunger but also giving your body the ammunition it needs to fight off harmful free radicals.

  • Rutile titanium dioxide is a lustrous, metallic mineral with a tetragonal crystal structure. Its name is derived from the Latin word rutilus, meaning red, although pure rutile is actually colorless or pale yellow. Impurities such as iron can give it a range of colors including brown, black, blue, and red. This mineral is not only significant for its appearance but also for its remarkable physical and chemical attributes.

  • Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. This form is selected when different properties, such as transparency and maximum ultraviolet light absorption, are required, such as in cosmetic sunscreens.
