Flame retardant wire and cable can be generally divided into general flame retardant wire and cable, low smoke, low halogen flame retardant wire and cable and low smoke halogen free flame retardant wire and cable.
At present, China's flame retardant wire and cable products containing halogen flame retardant, the wire and cable release large amounts of smoke and corrosive halide when burned, causing casualties and corrosion of various equipment, which is two times the so-called "disaster". In order to achieve low smoke, low toxicity and flame retardant, many domestic and foreign manufacturers are devoted to the development of low smoke, low halogen and low smoke halogen free flame retardant materials. Such materials burn less smoke, release less toxic gas, and reduce the damage to the human body and instruments and equipment. Overseas developed countries have studied the low smoke, low halogen, low smoke halogen free flame retardant wire and cable materials earlier, and the technology is more mature, and now it has entered the practical stage. Our country of low smoke and low halogen, especially the research and development of low smoke halogen-free flame retardant cable material is relatively late, the current study of low smoke halogen-free flame retardant cable material is still in the initial stage, some manufacturers have produced a low smoke halogen-free flame retardant cable materials, but most of the mechanical properties and processing the problem of poor performance.
At present, China's low smoke halogen free flame retardant wire and cable materials mainly rely on imports, the price is expensive, the application is subject to certain restrictions. With the rapid development of China's economic construction, the safety performance requirements increase, demand of non halogen flame retardant cable for low smoke more and more, many domestic manufacturers are increasing the intensity of low smoke halogen-free flame retardant cable material was developed. In 2002, the Ministry of Public Security issued a mandatory standard GA306-2001 "flame retardant and fire resistant cable, plastic insulated flame retardant and fire classification and requirements", on fire resistant cable are classified, and the fire-resistant cable smoke and smoke toxicity of the specific provisions of the standard system for flame retardant and fire in our country to further improve and promote on the promotion and application of flame retardant, flame retardant, high efficiency, no pollution to fire a. Low smoke halogen free flame retardant wire and cable material is the key development direction of flame retardant wire and cable in the future.
