Problems solved by technology

[0003] PVC rubber is widely used to make wire and cable materials due to its flame resistance, oil resistance, corona resistance, chemical corrosion resistance and good water resistance, but PVC rubber also has insufficient toughness, easy to break, poor flame retardancy, stretching The strength is not high, so adding reinforcing materials to make it have excellent flame retardancy and toughness is a technical problem that needs to be solved urgently in the existing technology
