Polyvinyl chloride (PVC) is the biggest characteristic of flame retardant, so is widely used in fire protection applications.But the polyvinyl chloride (PVC) in the process of combustion will release hydrogen chloride and other toxic gases, such as dioxin.
Polyvinyl chloride (PVC) combustion can be divided into two steps.In 240 ºC to 340 ºC before burning decomposition of hydrogen chloride gas and alkadiene contain a double bond, and then in 400-470 ºC carbon burning.
