Product Description
125 ℃ irradiated cross-linked polyolefin low smoke halogen-free cable material is made of polyolefin resin as the base material, with high-quality and efficient halogen-free flame retardants, cross-linking agents and other processing aids added. It is mixed, plasticized and granulated. It not only has excellent mechanical and physical properties, electrical properties, flame retardancy and processing performance, but also has the characteristics of halogen-free and low smoke generation. It is suitable for home decoration wires, power cables, control cables, optical cables, signal cables, etc. It has special high-temperature resistance properties such as short circuit non shrinkage and non foaming.
