What is 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.
Where is Tris(2,3-dibromopropyl) phosphate used?
- Plastics and polymer compounding: incorporated into polyurethane foams, polyester resins and thermoplastics for fire resistance in construction and automotive components
- Textiles and upholstery: flame-retardant finish for synthetic fabrics
- Electronics and electrical components: to achieve UL 94 flame ratings in housings and insulating materials
- Paper and leather processing: where surface flame retardancy was required
- Its use is now subject to significant regulatory restrictions in many markets.
Good to know: Restricted under REACH and other regulatory frameworks; availability is limited. Buyers should confirm regulatory compliance for their target market before placing orders.
