SAYTEX® RB-9170 Flame Retardant

CAS Number:  77098-07-8

SAYTEX RB-9170 flame retardant is a low-viscosity, reactive, aromatic bromine-containing diol with high bromine content. The product is a low-viscosity amber liquid with improved processing and storage characteristics compared to conventional brominated diols. Low viscosity at room temperature eliminates the need for heated, insulated storage tanks and drum-heating facilities. This patented proprietary product is the result of Albemarle technology that produces unique, high-aromatic-bromine-content diols in low-viscosity form.
