DR-M878 is a new high-efficiency flame retardant developed for polycarbonate (PC), suitable for preparing PC thin-walled flame retardant products, including films, sheets, thinsheets, and thin-walled injection molded parts. DR-M878 does not contain halogens and does not require the addition of PTFE anti-dripping agents, which can perfectly meet the regulatoryrequirements of fluorine/halogen-free deflationary.
