Description

technical field [0001] The invention relates to the technical field of low-density polyethylene plastics, in particular to a 70 degree Celsius insulation-grade soft polyethylene plastic. Background technique [0002] With the continuous deepening of my country's industrialization process, the electric power and communication industries have also undergone profound changes at the same time. As the foundation of the electric power and communication industries, wires and cables have higher and higher requirements. The performance and life of wire and cable depend on the selection of raw materials and technology of the product. At present, the common wire and cable materials are mainly plastics, and the most common and best-performing plastics are low-density polyethylene plastics. Low-density polyethylene plastic has excellent corrosion resistance, electrical insulation, and excellent flame resistance and self-extinguishing properties, so it has become an indispensable raw mat...
