OX0286 Micro-Titanium Dioxide (TiO2) Powder 1 000 μm (CAS No. 1317-80-2)

Micro Titanium Oxide (TiO2) Description

TiO2 is odourless and exhibits absorbency with a high refractive index, thereby demonstrating effective light-scattering properties. TiO2 is used in a variety of consumer and industrial products and is particularly applicable for uses requiring high levels of opacity, brightness and UV protection.

Main Features and Advantages:

1. UV Protection: Micro Titanium Oxide is known for its capacity to block ultraviolet radiation. It is a key ingredient in sunscreens and sunblocks, protecting skin from harmful UV exposure.
2. White Colour and Opacity: Its bright white colour and high refractive index contribute to increased opacity and brightness in pigments and coatings.
3. Photocatalytic Activity: In specific environmental applications, the photocatalytic properties of Micro Titanium Oxide are employed to break down organic contaminants and pollutants under light exposure, thereby improving air and water quality.
4. Antimicrobial Properties: Titanium dioxide nanoparticles exhibit antimicrobial effects and are utilised in antibacterial coatings, paints and medical devices.
