PC Retardant Masterbatch MB-PC20C
MB-PC20C (20%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, thin sheets, and thin-walled injection molded parts. MB-PC20C does not contain halogens and does not require the addition of PTFE anti-dripping agents, which can perfectly meet the regulatory requirements of fluorine/halogen-free deflationary.
