Featured inFlame Retardants

Bis(2-ethylhexyl) tetrabromophthalate (BEH-TEBP) is a liquid brominated FR plasticizer used in flexible PVC, polyurethane foams, and textile coatings where simultaneous flame retardancy and flexibility are required. Its liquid form and compatibility with PVC and polyurethane make it easy to incorporate without additional processing steps. BEH-TEBP provides moderate flame retardancy supplemented by antimony oxide synergist and is valued for its dual function as a plasticizer-flame retardant.
