Melamine Cyanurate (MC) Flame Retardant for Composite Materials

MC series flame retardant is a type of additive flame retardant, synthesized from melamine and cyanuric acid at a certain temperature, eco-friendly halogen-free nitrogen flame retardant, Non-toxic, odorless, and tasteless, with a high decomposition temperature (stable at 300 ℃), not only good flame retardancy, but a small amount of smoke during processing, good compatibility with polymer materials, and no surface migration phenomenon.
MC series flame retardant is suitable for polymer materials such as nylon, PB, PP, epoxy resin, organosilicon, polyester, rubber, etc.
The synergistic interaction of MC series flame retardant and phosphorus nitrogen flame retardants, which is also used in combination with other additives to achieve good flame retardant effects.
