Tributyl Phosphate, also known as phosphoric acid tri-n-butyl ester, is an organophosphorus compound serving as a high-efficiency polar solvent and plasticizer in heavy industrial applications. This chemical substance is primarily utilized as a metal extraction agent, particularly for the separation of rare earth elements and uranium, owing to its superior ability to form stable complexes with metallic ions. In industrial coating and ink formulations, it functions as a critical defoaming agent and air release additive, ensuring the integrity of polymer matrices and adhesive layers. We provide this material with competitive factory pricing, supporting requirements for customized specifications to meet rigorous purity standards for industrial scale-up. All shipments are accompanied by comprehensive MSDS, TDS, COA documentation to ensure regulatory compliance and are available for bulk supply for continuous manufacturing operations.
