Flame-retardant wire and cable can usually be divided into general c, low smoke low halogen flame retardant wire and low smoke halogen-free flame retardant wire and cable.
　　At present, China's flame-retardant wire and cable products to halogen-based flame retardant, this wire and cable in the combustion of the release of a large number of smoke and corrosive halide, causing casualties and corrosion of various equipment, the so-called "secondary disaster " In order to achieve low smoke, low toxicity and flame retardant purposes, many domestic and foreign manufacturers are committed to low smoke low halogen, low smoke zero halogen flame retardant material development.
　　China's low-smoke low-halogen, especially low-smoke halogen-free flame retardant wire and cable materials research and development relatively late, China's low smoke halogen-free flame retardant wire and cable materials research is still in the early stages, and some manufacturers have produced low smoke Halogen-free flame retardant wire and cable materials, but most of the mechanical properties and poor processing performance problems.
