LSZH cable compound

Low Smoke Halogen-Free Flame Retardant Polyolefin Compound for Cables

This cable compound features excellent mechanical strength and impact toughness, with resistance to repeated bending and vibration. It offers high insulation resistance and dielectric strength, ensuring stable power transmission with low energy loss. It also delivers superior anti-stress cracking performance, resisting thermal shock and chemical media corrosion. Additionally, it is flame-retardant and self-extinguishing, with low smoke and low toxicity, and no molten dripping during combustion. Finally, it has strong processing adaptability, suitable for extrusion, injection molding and other processes, with a high surface finish.
