Anatase titanium dioxide is characterized by its crystal structure, which is different from rutile. Anatase TiO2 particles are typically smaller and have different optical properties compared to rutile.
Titanium dioxide in the anatase form finds several applications in the PVC and leather industries, offering specific benefits and functions:
Whitening and Brightening: Anatase titanium dioxide is utilized as a whitening agent and brightener in PVC and leather applications. It helps achieve vibrant and consistent white coloration in PVC products such as pipes, profiles, and fittings, as well as in leather goods such as shoes, bags, and upholstery. Anatase TiO2 enhances the visual appeal of these materials by imparting brightness and opacity.
UV Protection: While anatase titanium dioxide may not offer the same level of UV resistance as rutile titanium dioxide, it still provides some degree of UV protection. In the PVC and leather industries, anatase TiO2 can help mitigate the effects of UV radiation on materials, reducing color fading, degradation, and embrittlement caused by exposure to sunlight. It contributes to the longevity and durability of PVC and leather products used in outdoor or high-UV environments.
Surface Enhancement: Anatase titanium dioxide is known for its ability to enhance the surface properties of PVC and leather materials. It can improve the smoothness, gloss, and uniformity of surfaces, creating a more attractive and aesthetically pleasing appearance. In the leather industry, anatase TiO2 may be used in finishing treatments to achieve desired surface effects and textures.
Functional Additive: Anatase titanium dioxide can serve as a functional additive in PVC and leather formulations, offering benefits beyond coloration and aesthetics. It may contribute to the mechanical properties, thermal stability, or processing characteristics of PVC and leather materials, depending on the specific formulation and application requirements. Anatase TiO2 can enhance the performance and functionality of PVC and leather products in various end-use applications.
Compatibility and Versatility: Anatase titanium dioxide is compatible with a wide range of polymers, additives, and processing conditions commonly used in the PVC and leather industries. Its versatility allows for flexible formulation options to meet specific performance and regulatory requirements. Anatase TiO2 can be incorporated into PVC compounds, leather finishes, coatings, and adhesives to achieve desired performance attributes and aesthetic effects.
