Polyvinyl chloride (PVC, or vinyl) materials or products tend to have excellent fire performance properties.In particular, pure PVC will not burn once the source of heat or flame is removed.

This is because 56.8% of the base polymer weight of PVC is chlorine.It is well known that chlorine is one of the few elements that confers good fire properties to a polymer.

Unplasticized (rigid) vinyl materials,such as those used for making pipe,siding or vertical blinds, cause less fire hazard
