Retardant wire and cable usually can be divided into general retardant wire and cable, low smoke and low halogen flame-retardant wire and cable and low smoke zero halogen flame-retardant wire and cable.
    Of flame retardant wire and cable products to halogen-containing flame retardant mainly this wire and cable when burned, release a lot of smoke and corrosive halide to causing casualties corrosion variety of devices, the so-called "secondary disasters . "To achieve low smoke, low toxicity, and flame-retardant purpose, many domestic and foreign manufacturers are committed to the development of LSF, LSZH flame retardant materials. Such materials less smoke when burned, release fewer toxic gases, to reduce the harm to the human body and equipment. Developed countries LSF, LSZH flame retardant wire and cable compounds earlier, the technology is more mature, and now has entered a practical stage. Our low smoke and low halogen, late especially LSZH flame retardant wire and cable materials research and development, China LSZH flame retardant wire and cable materials research is in its infancy, some manufacturers produce low smoke halogen-free flame retardant wire and cable materials, but most of the existence of the problem of poor mechanical properties and processing performance.

    LSZH flame retardant wire and cable materials are mainly dependent on imports expensive, the application subject to certain restrictions. With the rapid development of China's economic construction and the improvement of safety performance requirements, LSZH flame retardant wire and cable demand is growing, many domestic manufacturers intensify LSZH flame retardant wire and cable materials developed. In 2002, the Ministry of Public Security issued a mandatory standard GA306-2001 flame retardant and fire-resistant cable: plastic insulated fire-retardant and fire-resistant cable grading and requirements ", graded fire-resistant cable, the amount of smoke and fire-resistant cable and smoke toxicity made specific provisions to further improve the standard of our fire retardant and fire-resistant cable system, the promotion and application of fire retardant, efficient, pollution-free flame-retardant, fire-resistant cable has played a role in the promotion. LSZH flame retardant wire and cable materials retardant wire and cable in the future focus on the development direction.
