Book excerpt: Handbook of UV Degradation and Stabilization, Third Edition, discusses different aspects of UV-related phenomena that occur when polymeric materials are exposed to UV radiation. It reviews existing literature, looking at how plants, animals and humans protect themselves against UV radiation. This review permits evaluation of mechanisms of protection against UV used by living things and potential application of these mechanisms in the protection of natural and synthetic polymeric materials. Other chapters look at more specific aspects of UV degradation and stabilization, such as specific polymers and rubbers, analytical methods used in UV stabilization, health and safety, and more. This book is an excellent companion to the Databook of UV stabilizers which has also been published recently. Both books supplement each other without repeating the same information – one contains data another theory, mechanisms of action, practical effects and implications of application. Provides a practical reference guide for engineers and scientists who design with plastics and formulate plastic materials Explains the effect of UV light on plastics and how to mitigate its effects through the use of UV stabilizers Surveys the range of UV stabilizers on the market and provides advice on their selection and use
