SAYTEX RB-49 flame retardant is a highly efficient reactive aromatic bromine source. In some cases SAYTEX RB-49 flame retardant’s derivatives can be substituted for higher bromine-containing flame retardants on an equal weight % basis rather than an equal % bromine basis. SAYTEX RB-49 flame retardant allows for the highest level of bromine to be reacted into unsaturated polyesters at comparable monomer levels.
