At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.

Anatase, on the other hand, has an orthorhombic crystal structure and a lower refractive index than rutile. Despite these differences, anatase also possesses excellent photocatalytic properties, making it a promising material for environmental applications such as water treatment and air purification. In addition, anatase's higher surface area and reactivity make it suitable for use in cosmetics, sunscreens, and other personal care products.

At present, the equipment and manufacturing process of domestic manufacturers of polyvinyl butyral are constantly getting closer to those abroad. For example, the wonderful use of polyvinyl butyral (PVB) has occurred in the printing industry and ceramic industry. Therefore, the domestic application of polyvinyl butyral (PVB) has an obvious upward trend in recent years.

For example, in the glass industry, it is because polyvinyl butyral (PVB) has good low-temperature impact strength, windability, light transmittance, light resistance, weather resistance, sound insulation, UV insulation and other properties, so that once the laminated glass is sealed together, the glass sandwich (i.e. laminated material) will appear as a whole and look like ordinary glass. For example, in the porcelain industry, polyvinyl butyral is made into a film and used for printing paper film of ceramic (or enamel) products. First, it reduces the original glue small paper Decal process, reduces the production cycle and production cost, and second, it makes its ceramic (or enamel) patterns bright in color and smooth in texture.

With the rapid development of science and technology in recent years, more and more industries have found the characteristics of polyvinyl butyral (PVB): high strength, high toughness, fatigue resistance, corrosion resistance and so on. Compared with traditional materials, polyvinyl butyral (PVB) is more and more widely used because of its larger development space and wider application fields!

Application field of polyvinyl butyral -- safety glass

The membrane made of polyvinyl butyral (PVB) is a special product used to manufacture safety glass and bulletproof glass. Safety glass is a special glass made of a layer of PVB diaphragm sandwiched between two layers of ordinary glass. It has good low-temperature impact strength, windability, light transmittance, light resistance, weather resistance, sound insulation, ultraviolet insulation and other properties. When subjected to strong external impact, PVB diaphragm can absorb impact energy, so that the glass will not break or prevent debris from hurting people. Moreover, the safety glass added with PVB diaphragm has the characteristics of high transparency, water resistance and aging resistance, and can be used in the environment of - 60 ℃. In addition, it can also be used as transparent material to replace plexiglass.
