PPT ATH is a high-value, halogen-free flame-retardant material used in Halogen-Free Flame Retardant (HFFR) cables, polymer insulators, thermal insulation, composites and paints. In cable applications, it helps suppress flame propagation and smoke generation without releasing halogen acid gases, supporting safer electrical and infrastructure systems.
