The invisible threat of traditional cables, the fatal cost behind burning<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The insulation layer of traditional cables is mostly made of polyvinyl chloride (PVC), and its flame retardancy depends on halogen additives. Once a fire breaks out, These halogen-containing materials will release\u00a0toxic gases such as hydrogen chloride and dioxins\u00a0and produce a lot of black smoke. Thick smoke can reduce visibility to less than 1 meter within 30 seconds, and hydrogen chloride forms hydrochloric acid when it meets water, which further corrodes firefighting equipment and the human respiratory tract.<\/p>\n<p>More seriously, such cables are very likely to cause a \u201cchimney effect\u201d in confined spaces such as high-rise buildings and subway tunnels, accelerating the spread of fire. In the 2003 Daegu subway arson case in South Korea,\u00a0toxic gases released by the burning of PVC cables\u00a0were identified as one of the main causes of casualties.<\/p>\n<h3 id=\"02-material-revolution-from-halogen-containing-flame-retardant-to-halogen-free-and-environmentally-friendly\"><span class=\"ez-toc-section\" id=\"2_Material_revolution_from_halogen-containing_flame_retardant_to_halogen-free_and_environmentally_friendly\"><\/span>2.
