Flammability of pvc

WebPVC is highly flammable, and when burned in waste heaps or in accidental fires, PVC off-gases toxic fumes, dioxins, and hazardous chlorine gas. The myth about vinyl off-gassing toxic fumes can be easily addressed by pointing out three widely recognized properties of vinyl. 1) Vinyl building products exhibit WebPVC is sometimes referred to as vinyl or polyvinyl chloride. This thermoplastic compound consists of three types of vinyl compounds: standard, semi-rigid, and irradiated. The formulation's rated temperature may vary from -55 C to 105 C.
