Overview
Eastman TEP (triethyl phosphate, CAS No. 78-40-0, chemical formula C6H15O4P) is a process solvent that can also be used as a plasticizer for tough, fire-resistant plastics. Triethyl phosphate is commonly used as an intermediate for agricultural chemicals when preparing TEPP (tetraethyl pyrophosphate). Triethyl phosphate is also an effective viscosity reducer for unsaturated polyester resins for fiberglass-reinforced plastic, aliphatic polyester polyols for urethane foams, aromatic polyester polyols and sucrose-amine polyols for rigid urethane foams, and acrylic resins and saturated polyester resins for high-solids protective coatings. Triethyl phosphate is also used in the oil field industry as an oil extraction aid, and as an intermediate chemical in the manufacture of fracturing gels.
