GFLAM-APP10 is an Ammonium Polyphosphate (APP) Type I halogen-free flame retardant, optimized for intumescent flame-retardant (IFR) systems in thermoplastics such as polypropylene (PP), polyethylene (PE), and EVA. It promotes rapid char/foam layer formation under heat exposure, creating an insulating barrier that reduces heat transfer and slows the diffusion of oxygen and volatile fuel to the flame zone. With low water solubility and a high thermal decomposition onset, GFLAM-APP10 is well suited for extrusion and injection molding where stable processing and consistent FR performance are required in HFFR formulations.
GFLAM-APP10 functions as an acid source and blowing/char-promoting component within IFR systems, typically used with compatible carbon sources (polyols) and nitrogen synergists to build a cohesive, expanded char. The intumescent shield helps reduce flame spread and can improve anti-dripping behavior in polyolefin systems when the overall formulation is balanced. GFLAM-APP10 supports cleaner halogen-free fire performance compared with conventional halogen/antimony packages, making it relevant for applications targeting reduced corrosive smoke. It is engineered to disperse effectively in polyolefin matrices with appropriate coupling/dispersion aids, supporting consistent melt flow and molded surface quality. In EVA and PE compounds, it can be used to develop halogen-free cable compounds and molded parts where a balance of mechanical properties and flame retardancy is needed. Final FR rating (e.g., UL 94) depends strongly on polymer type, filler level, synergists, and part thickness, so loading should be optimized through lab and application trials. Typical end-uses include HFFR polyolefin compounds for wire & cable, appliance and electrical housings, automotive interior parts, construction profiles, and general-purpose molded components requiring intumescent fire protection.
