Flame Retardants, Polypropylene (PP)

PPV2-8H Bromine–Phosphorus Flame Retardant Masterbatch

PPV2-8H is a high-efficiency bromine–phosphorus synergistic flame retardant masterbatch designed for polypropylene systems including homopolymer PP, copolymer PP, recycled PP, and toughened PP blends. Its high thermal stability and controlled bromine content provide strong flame performance at low addition levels. PPV2-8H maintains colour stability, mechanical properties, and clean processing behaviour, making it a cost-effective and reliable flame-retardant solution for molded and extruded PP applications.
