Home - Zinc Oxide Product Portfolio | RBH Ltd Zinc Oxide High purity zinc oxide functional mineral offering UV protection, heat stabilisation, pigment and activator performance across coatings, polymers, rubber and industrial applications. CAS NUMBER: 1314-13-2 Request A Sample Names Zinc Oxide|Zinc Oxide Powder|Zinc White Chemical formula ZnO Product Overview Zinc Oxide is a versatile functional mineral widely used across coatings, polymers, rubber and industrial systems. It offers UV protection, heat stabilisation performance, pigment modification and activator properties in vulcanisation and polymer cure systems. In coatings, zinc oxide improves opacity and weather resistance while contributing to film protection and durability. In plastics and thermoplastics, it functions as an effective heat stabiliser and modifier, supporting colour stability and resistance to thermal degradation during processing. In rubber systems, zinc oxide acts as a key activator in vulcanisation, improving cure efficiency and mechanical performance. Additionally, zinc oxide is used in personal care applications as a broad spectrum UV absorber and skin protectant. RBH supplies high purity zinc oxide grades with consistent particle size and controlled purity to support reliable performance in demanding formulation environments.
