MC-A Flame Retardant for Composite Materials

MC-A 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, especially for composite materials.
It’s 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-A flame retardant is easy to disperse due to hydrophilic surface, suitable for flame retardancy in polymer materials such as epoxy resin, organosilicon, polyester, etc.
MC-A flame retardant has compounded with OPA series in a certain formula ratio to form a new phosphorus ammonia halogen-free flame retardant. Through a synergistic effect of phosphorus and nitrogen, the whole is greater than the sum of the parts.
