Problems solved by technology

[0003] At present, high flame-retardant PVC sheathing materials used in the field of wire and cable widely exist in China, but a large amount of plasticizers are generally used in conjunction with a large amount of flame retardants to achieve better low-temperature performance of PVC materials. Even if it can pass the test, the material will be broken into pieces after burning, and it is difficult to protect the inside of the cable
However, the price of imported products is particularly high, and the cost pressure of cables is relatively high.
