Composite Flame Retardant for PP

Polypropylene (PP), as one of the general-purpose plastics with a great output, has a wide range of applications in various industries. However, the flammable characteristics of PP materials also limit their application space and hinder the further development of them. Therefore, the flame retardant modification of PP has been the focus of attention.

Composite Flame Retardant for PP

Alfa Chemistry offers a series of composite flame retardants for PP, which are suitable for copolymerized PP or homopolymerized PP. They are halogen-free and environmentally friendly flame retardants with phosphorus, nitrogen, and bromine as the main flame retardant elements. They can be widely used in the flame retardancy of PP materials such as bellows, hollow boards, building templates, automotive interior plastic parts, decorative panels, plating tanks, injection molding parts, extrusion plates, blown films, cast films, etc.
