Tris(2-ethylhexyl) phosphate

Tris(2-ethylhexyl) phosphate (CAS 78-42-2), commonly abbreviated as TEHP, is an organophosphate ester used across industrial manufacturing as a plasticizer, flame retardant, and solvent. Its low volatility and high boiling point make it a preferred choice where thermal stability and long-term performance in finished products are critical procurement considerations for chemical buyers.

In plastics and polymer processing, TEHP functions as a non-halogenated flame retardant and plasticizer in PVC, rubber, and synthetic resins, improving flexibility while meeting fire performance requirements. Coatings and adhesives manufacturers incorporate it as a solvent and plasticizing agent to control viscosity, film formation, and substrate adhesion in various industrial formulations and applications.

The textile and leather industries use TEHP as a processing aid and finishing component, where its compatibility with synthetic fibers and surface treatments supports durable end-product performance. In lubricants and metalworking fluids, it acts as an extreme-pressure additive and functional solvent, extending fluid service life under demanding operating conditions and high-stress environments.

TEHP is supplied as a clear, low-viscosity liquid in drum and IBC quantities, with bulk tanker options available for high-volume procurement and large-scale industrial manufacturing needs. It is offered in technical grade as the standard commercial specification across most supply channels. Purity levels typically range from 99% and above, with documentation including COA and TDS.
