FR-130 Flame Retardant for EPS/XPS – ST-130
Product Overview
ST-130 is an FR-130 type brominated flame retardant (CAS No. 97416-84-7) designed for EPS and XPS applications. It provides high bromine content, good thermal stability and efficient flame-retardant performance, making it a practical HBCD alternative for polystyrene foam insulation.For another polymeric flame retardant solution for EPS/XPS, see our Brominated SBS – ST-970.
