PC flame retardants

PC Flame Retardant DR-M878

Inovia DR-M878 is a 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. DR-M878 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.

Note: The film casting machine we used, is a small experimental type without vacuum pump, which leading to a number of crystal point bubbles present in the film. And that maybe effect the properties. The data above is only for reference.
