Clariant Exolit AP 740 is a white free-flowing powder Flame Retardants utilizing phosphorus-nitrogen synergistic technology to deliver superior flame retardancy. This halogen-free solution forms an insulating char layer during combustion, effectively blocking heat and oxygen transmission. Specially engineered for thermoset resins, it simultaneously addresses primary fire risks and secondary hazards like smoke emission, making it ideal for applications demanding comprehensive fire protection.
