Polyurethane flexible foam fire resisting by melamine and expandable graphite: Industrial approach

According to importance of the safety issues especially in air industry, fire-resisted parts and interiors consumption are increasing. Seat foam has a huge fraction of the airplane interior and this makes it essential to become safer. From another point, planning to phase out some of the halogenated flame retardants because of persistence in the environment, bioaccumulation, and toxicity. In recent years, halogen-free fire retardants have been more investigated. In this work, we have concentrated more on two well-known, solid, halogen-free fire retardants, expandable graphite and melamine, and compared their performance according to their fire behavior, physical properties, and production phenomena.
