Tris(2-chloroethyl) Phosphate, widely known by its acronym TCEP and identified by CAS number 115-96-8, is a chemical compound of significant industrial importance, primarily recognized for its capabilities as a flame retardant and plasticizer. Understanding its chemical profile is key for professionals in material science, R&D, and procurement looking to leverage its properties.

Chemically, TCEP is an organophosphate ester with the molecular formula C6H12Cl3O4P. Its structure features a central phosphorus atom double-bonded to an oxygen atom and single-bonded to three 2-chloroethoxy groups. This specific arrangement of chlorine and phosphorus atoms is fundamental to its effectiveness in flame retardancy. The theoretical chlorine content is approximately 37.3%, and the phosphorus content is around 10.8%, both crucial contributors to its fire-inhibiting mechanism.

Physically, TCEP is typically described as a colorless to light yellow, oily transparent liquid. It possesses a relatively low freezing point and a high boiling point, indicating stability under various processing conditions. It is soluble in common organic solvents such as ethanol, ethyl acetate, and toluene, but it has limited solubility in water and is insoluble in aliphatic hydrocarbons. This solubility profile influences its incorporation into different polymer matrices. Its viscosity at 20°C is in the range of 34-47 mPa·s, and its relative density is around 1.426, as per common specifications.

The primary application of TCEP is as an additive flame retardant. It is particularly effective in polymers like polyurethane, polyvinyl chloride (PVC), polyester resins, and acrylic resins. In these materials, TCEP acts by disrupting the combustion process, often through mechanisms involving the release of flame-inhibiting gases and the formation of a protective char layer. This greatly enhances the fire safety of the final products, making them suitable for applications where fire resistance is critical, such as in building materials, automotive components, and textiles.

Furthermore, TCEP functions as a flame retardant plasticizer. This means it not only confers fire resistance but also improves the flexibility, processability, and other physical properties of the polymer. This dual role makes it a cost-effective solution for manufacturers seeking to optimize material performance and safety simultaneously. For instance, in PVC applications, it can contribute to both self-extinguishing properties and a softer feel.
