Tris(2,3-dibromopropyl) phosphate

Tris(2,3-dibromopropyl) phosphate (CAS 126-72-7), also known as TDBPP or Tris-BP, is a reactive and additive halogenated flame retardant used to reduce flammability in polymer systems and treated materials. Historically applied across multiple industrial sectors, its use is now subject to significant regulatory restrictions in many markets due to environmental and toxicological concerns that procurement teams must evaluate before sourcing.

In plastics and polymer compounding, TDBPP was incorporated into polyurethane foams, polyester resins, and thermoplastics to meet fire resistance standards in construction and automotive components. Textile and upholstery manufacturers applied it as a flame-retardant finish for synthetic fabrics, particularly in applications requiring compliance with flammability testing requirements.

Electronics and electrical component producers used it to achieve UL 94 flame ratings in housings and insulating materials. Paper and leather processing operations also employed it where surface flame retardancy was required. Tris-BP is supplied as a liquid at standard commercial concentrations. Technical grade is the primary form available through specialty chemical distributors for industrial applications.

Due to its restricted status under REACH and other regulatory frameworks, availability is limited, and buyers should confirm regulatory compliance for their target market before placing orders.
