Problems solved by technology

[0002] With the rapid development of the domestic cable industry, conventional cable materials can no longer fully meet the increasingly diverse needs of cable factories. In order to meet high flame-retardant requirements, the amount of flame retardant added to current cable materials is too large. During the cable extrusion process, the current extrusion is too high, the extrusion speed is too slow, and the energy consumption is too large.
