低烟无卤阻燃聚烯烃电缆料性能、挤塑设备及工艺推荐（Low smoke halogen free flame retardant polyolefin cable material performance, extrusion equipment and process recommendation） Low smoke halogen free flame retardant polyolefin cable material performance, extrusion equipment and process recommendation Wuxi jieke plastic industry co. LTD Abstract: this article in view of the low smoke zero halogen flame retardant polyolefin cable material from formula technology, performance, extrusion equipment and technology from several aspects such as analysis, hoping to zero halogen flame retardant polyolefin cable manufacturers to provide the reference, in order to better choose halogen-free cable material varieties, extrusion equipment and make reasonable extrusion process. Along with our country, metallurgy, electric power, electronics, automation and the rapid development of information network and other industries, has to match the wire and cable, especially the amount of flame retardant wire and cable has increased dramatically, including power cable, control cable, signal cable, instrumentation cable, computer cable etc. Polyvinyl chloride (PVC) as a commonly used traditional flame retardant cable sheath, although PVC material has good flame retardancy, low price and good extrusion process, but due to its containing halogen, the combustion will release a large number of halolide gases and smoke, secondary hazard of fire, thus increased the fire loss. Especially a lot of scientific research has confirmed that halide to human health and the environment caused by the damage has become more and more serious, people pay more and more attention to environmental protection, the eu and some big Japanese company Sony, Toshiba, etc are put forward to restrict the use of PVC regulations; At home, in March 1998, the Beijing power supply bureau dispatch rules prohibit PVC wire and cable used in the agency system, the east China architectural design and research institute 2002 and launched the civil building wir
