Problems solved by technology

[0004] Halogen-containing flame retardant substances will produce non-degradable or refractory toxic substances (such as dioxin-like organic halogen chemicals) when burned, polluting the environment and affecting human and animal health
[0005] Due to the addition of organophosphate and / or phosphorus-nitrogen intumescent flame-retardant system in the existing halogen-free flame-retardant cable materials, the mechanical properties are greatly reduced, the flame-retardant grade is low, and the temperature resistance grade is low.
