2-ethylhexyl 2,3,4,5-tetrabromobenzoate

2-Ethylhexyl 2,3,4,5-tetrabromobenzoate (CAS 183658-27-7), commonly referenced in the market as EH-TBB or TBB, is a brominated aromatic ester used as a non-polymeric flame retardant.

It functions by interrupting combustion in polymer matrices, helping end products meet fire safety standards. In flexible polyurethane foam, EH-TBB is a primary component of next-generation flame retardant blends.

These blends were developed as alternatives to legacy brominated compounds, particularly in furniture and bedding applications. Textile back-coating formulations incorporate it to achieve flame resistance.

This is particularly useful in upholstery fabrics and curtains without compromising flexibility. In plastics processing, it is compounded into soft PVC and engineering resins where halogenated flame retardancy is required.

Leather and paper treatments also utilize TBB where surface-applied flame retardant finishes must meet specific regulatory or commercial fire standards. It is supplied as a liquid or low-viscosity fluid.

This physical state makes it suitable for direct blending into foam systems and coating formulations. It is available in technical grade, with purity specifications typically confirmed by bromine content and ester assay.

Bulk and drummed packaging options are standard for industrial supply chains. This ensures efficient logistics and handling for large-scale manufacturing operations across various chemical sectors.
