Tris(2-chloroethyl)phosphate

Tris(2-chloroethyl)phosphate (CAS 115-96-8), commonly abbreviated as TCEP, is a chlorinated organophosphate flame retardant used across a broad range of polymer and coating systems.

It functions as both a reactive flame retardant and plasticizer, reducing flammability in finished materials while contributing to processing flexibility in various industrial manufacturing sectors.

In rigid and flexible polyurethane foams, TCEP imparts flame retardancy to insulation panels, upholstery components, and construction boards where fire performance standards must be met.

Coating formulators incorporate it into intumescent and protective coatings for metal, wood, and concrete substrates in building and construction applications for enhanced safety.

Textile and nonwoven manufacturers apply TCEP-based treatments to technical fabrics used in automotive interiors and protective workwear requiring compliance with fire safety regulations.

Adhesive and sealant producers use it in formulations where both flame retardancy and low-temperature flexibility are required, particularly in aerospace and defense assembly applications.

TCEP is supplied as a clear to pale yellow liquid, typically in drum and IBC quantities for industrial buyers. It is available in technical grade for flame retardant applications.

This specification is the standard for coatings, polymers, and textiles. Bulk tanker supply is available for large-volume procurement in high-capacity manufacturing environments.
