135℃ LSHF/LSZH Flame-Retardant Irradiation-Crosslinkable Polyolefin Insulation Compound

135℃ LSHF/LSZH Flame-Retardant Irradiation-Crosslinkable Polyolefin Insulation Compound

135℃ LSHF/LSZH Flame-Retardant Irradiation-Crosslinkable Polyolefin Insulation Compound is mainly made of halogen-free non-toxic modified polyolefin resin as the main raw material, with the addition of environmentally friendly flame retardants, heat stabilizers, smoke suppressants, mold inhibitors and other additives. It is produced through mixing, extrusion, and granulation. This material has good processing performance, physical and mechanical properties, insulation performance, and excellent flame retardant properties. It does not release halogen acid and self extinguishes upon ignition, which can greatly reduce the emission of toxic and corrosive gases and the generation of smoke. After immersion in water, the insulation resistance changes little, and it has high safety and reliability when made into cables.
