摘要

The high chlorine content (56.8%) of PVC makes it relatively resistant to ignition and burning. For many applications of rigid PVC, no additions of flame-retardant (FR) or smoke suppressant (SS) additives are required. PVC is compatible with a wide range of formulating ingredients such as plasticizers which make it flexible and less resistant to ignition unless FR and SS additives are incorporated. Many FR and SS materials work synergistically with each other and with PVC in formulations which pass stringent FR specifications cost effectively. The information presented and referenced relates mainly to the North American market where FR/SS PVC is successful based on superior cost-performance. Some of the political efforts in Europe to ban or phase out plastics containing organically bound halogens either as additives or on the polymer backbone are discussed briefly as threats to achieving improved real-world fire safety.
