Problems solved by technology

[0002] As society pays more and more attention to fire hazards, the fire performance of cables is also required to be higher. Some special flexible cables (such as elevator cables, telecommunication device cables, etc.) also require certain thermal stability. With the application range of wire and cable The continuous expansion of the cable material has higher and higher performance requirements, especially the thermal stability of the cable material in the prior art needs to be further improved
