The use of polymers by their flammability – they may indeed initiate or propagate fires. Halogen-based retardants are providing unsatisfactory, despite their effectiveness and versatility, due to associated problems with health and environmental impact. Intumescent systems are an alternative investigation, and Fire Retardancy of Polymers: The Use of Intumescence is the first book on this fascinating subject. These materials from a blown protective cellular char on thermal degradation, which is not only effective but also environmental friendly. The mechanisms involved in the process and the analytical techniques used for the characterisation of the charred materials are presented from international studies. With extensive references, this book provides a comprehensive and up-to-date view on this emerging field. It will be a useful tool for further research and development work by many professional and researchers in industry and academia with an interest in polymer science and safety hazards.
