125℃ LSHF Flame-Retardant EPDM Elastomer Irradiation-Crosslinkable Insulation Compound

125℃ LSHF Flame-Retardant EPDM Elastomer Irradiation-Crosslinkable Insulation Compound

125℃ LSHF Flame-Retardant EPDM Elastomer Irradiation-Crosslinkable Insulation Compound is mainly formulated with halogen-free non-toxic modified EPDM rubber as the base polymer, compounded with various additives. Through mixing and extrusion pelletization processes, it achieves exceptional processability, physical-mechanical properties, electrical insulation performance, and outstanding flame retardancy. During combustion, it releases no halogen acids and exhibits self-extinguishing behavior upon flame removal, significantly reducing toxic corrosive gas emissions and smoke generation. Cables manufactured with this material develop a smooth, rounded surface with superior elasticity and tactile quality after irradiation crosslinking. It is ideally suited for control cables and instrumentation cables.
