  • One of the key advantages of P25 TiO2 is its ability to provide excellent UV protection. It effectively absorbs ultraviolet light, which can cause damage to many materials and products over time. By incorporating P25 TiO2 into coatings, plastics, and other materials, manufacturers can enhance their products' durability and longevity by protecting them from harmful UV radiation.



  • 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.

  • The journey of TIO2 begins with mining raw materials, primarily ilmenite, rutile, and anatase minerals, which are then processed through various methods including the chloride process or the sulfate process. The chosen procedure significantly impacts the final characteristics of the TIO2 pigment, such as its particle size, distribution, and crystalline structure, which in turn affect its optical properties.
  • R960 is particularly well-suited for use in TiO2 manufacturing processes due to its ability to enhance the performance of catalysts used in the production of TiO2.

  • There seems to be a lot of misunderstanding about titanium dioxide, which can be used as a colorant in foods. While headlines may suggest titanium dioxide is a health concern, scientific research has actually shown titanium dioxide to be safe. So what is it used for and why is it used? Read on to learn more!

  • In conclusion, China's titanium oxide industry has become a vital part of the country's economy, as it continues to produce high-quality pigment for a wide range of applications. With its strong position in the global market and ongoing efforts to improve sustainability, China is set to maintain its leading role in the production of titanium oxide for the foreseeable future.

  • The titanium dioxide market fluctuated in the first two quarters of 2023. These pricing patterns resulted from poor demand and reduced intakes from the downstream industries. Amid the slow demand, the manufacturers were forced to reduce their outputs. With rising inflation rates, production cuts gradually increased. Given the economic downturn, the labor strikes further affected the market dynamics, thereby exerting pressure on the pricing fundamentals.

  • However, the use of titanium dioxide in plastic factories requires careful consideration of particle size, surface treatment, and dispersion techniques to achieve optimal performance. Manufacturers must balance the desired properties against potential challenges such as agglomeration or increased viscosity during processing.
