tris(2-butoxyethyl) phosphate
Tris(2-Butoxyethyl) Phosphate (TBEP, CAS: 78-51-3) is a low-viscosity, non-halogenated phosphate ester. Widely regarded as a versatile plasticizer and flame retardant, TBEP offers excellent compatibility with various polymers, enhancing flexibility and durability. It is a key ingredient in floor polishes, hydraulic fluids, and synthetic rubber products.
TBEP’s primary applications leverage its dual functionality. It is extensively used in floor polishes and waxes to improve gloss, slip-resistance, and leveling properties. As an effective flame retardant, it is incorporated into synthetic resins and plastics like PVC and polyurethane to meet stringent fire safety standards. Additionally, TBEP serves as a functional hydraulic fluid component and a specialized anti-foaming agent in industrial detergents, contributing to high performance and safety across manufacturing, automotive, and maintenance sectors.
