Overview
Chemours Titanium Dioxide (TiO2) is a premium-grade white pigment produced by The Chemours Company, a global leader in chemical solutions. It is renowned for its exceptional opacity, brightness, and durability, making it indispensable in industries requiring high-performance pigments. The product is available in both rutile and anatase crystalline forms, with rutile being the more stable and widely used variant. TiO2 is chemically inert, non-toxic, and resistant to UV radiation, which enhances the longevity of products it is incorporated into. Its versatility extends across coatings, plastics, paper, and even food and cosmetic applications, where it serves as a whitening and opacifying agent.
Physical and Chemical Properties
Chemours Titanium Dioxide exhibits a high refractive index (2.7 for rutile), which contributes to its superior opacity and scattering efficiency. This property is critical for applications like paints, where maximum coverage with minimal material is desired. The powder is insoluble in water and most organic solvents, ensuring stability in diverse formulations. Thermally, TiO2 is highly stable, with a melting point of 1843°C and a boiling point of 2972°C. Its UV absorption capabilities make it a key ingredient in sunscreens and outdoor coatings, where it protects substrates from degradation. The material’s chemical inertness also ensures compatibility with a wide range of binders and resins.
Main Applications
In the coatings industry, Chemours TiO2 is a cornerstone for architectural and industrial paints, providing whiteness, gloss, and weather resistance. Plastics manufacturers rely on it to enhance opacity and brightness in products like PVC pipes, packaging films, and automotive parts. The paper industry uses it to improve printability and brightness in high-quality papers. Beyond traditional uses, TiO2 is found in cosmetics (e.g., foundations, sunscreens) for its light-scattering properties and in food-grade applications as a colorant (E171). Its photocatalytic variants are also employed in self-cleaning surfaces and air purification systems, though these require specific formulations to avoid unintended reactivity.
Safety and Storage
While TiO2 is generally considered safe, inhalation of fine dust particles should be avoided, as it may cause respiratory irritation. Proper PPE, including masks and gloves, is recommended during handling. The powder is non-flammable and non-reactive under normal conditions, but prolonged exposure to moisture can lead to clumping. Storage should be in a dry, cool environment, away from direct sunlight and incompatible materials like strong acids or alkalis. Bulk shipments typically come in 25-kg bags or supersacks, which should be inspected for damage upon receipt to prevent contamination.
B2B Procurement Guide
When sourcing Chemours Titanium Dioxide, prioritize suppliers with verified certifications (e.g., ISO 9001) to ensure product consistency and traceability. Key specifications to confirm include crystalline phase (rutile/anatase), purity (≥90% for industrial grades), and surface treatments (e.g., silica/alumina coatings for dispersion). Pricing is influenced by global TiO2 market trends, with premiums for specialty grades like those for cosmetics or food contact. Volume discounts are common for large orders, but lead times can vary due to production cycles. Consider regional logistics—shipping costs for bulk quantities may impact total procurement costs significantly.
