为什么要选择低烟无卤导管？

Why choose low smoke and halogen free conduit? What are the differences between normal PVC and halogen conduits? -Low smoke: Smoke caused by burning plastics poses a massive threat to human lives. PVC Conduits can never comply with low smoke requirements due to material properties. -Flame retardancy: To avoid flame propagation in buildings, conduits have to be flame retardants. While halogen free conduits need specific additives. PVC is genuinely flame retardant. -Zero Halogen: In case of fire, halogens generate toxic smoke. Halogen free installation systems eliminate this hazard. PVC contains halogen chlorine and is never halogen-free. Environmental protection, halogen-free, non-toxic, low smoke. Dedicated to hospitals, school dormitories, airports, and other projects.
