A practical, comprehensive resource on the complex behaviors of plastics written expressly for conservation and cultural heritage professionals.
 
Almost every museum in the world is confronted with plastics in their collections. Research initiatives and knowledge concerning the conservation of heritage objects made of plastics have proliferated over the last twenty-five years, necessitating this up-to-date, comprehensive resource. Intended as a highly practical guide for the conservation community, this authoritative book offers information essential to understanding plastics, polymers, and rubber/elastomers and their behaviors in the cultural heritage context. Numerous graphs, diagrams, and illustrations allow readers to compare the mechanical, physical, thermal, and optical properties of these substances during conservation. Aimed at the hands-on museum practitioner, this book will assist professionals in choosing the appropriate methods and materials for preserving and treating plastic objects.
 
Complementing the main chapters, fifty-six illustrated “fact sheets” summarize, at a glance, the properties of those plastics most commonly found in museum collections. Six informative case studies present real-world examples of current conservation approaches to works of art and design made of plastics and rubber/elastomers. Under the expert authorship of Thea B. van Oosten, conservation scientist, educator, and internationally regarded authority on the behavior and properties of plastics, this instructive volume is destined to become an invaluable resource for the field.

Flexible Polyurethane (PUR) foams, in use since the 1950s and familiar from furniture upholstery and other domestic textiles, can be found in museum collections in numerous art and design objects. However, these exhibits pose severe conservation problems due to the ageing of the foam caused by photo-oxidation, leading to discoloration, loss of strength and fl exibility, and fi nally the crumbling of the object. This defi nitive work outlines the most up-to-date methods of restoring fl exibility of older foams and protecting new foams from degradation by coating them with stabilising systems acting effectively as a ‘sunblock’. The author, an experienced conservator, describes the research involved in developing the new methods and their impact on the visual, textural and chemical properties of treated PUR foams. One of the chapters details the preparation and application of the light stabilizing system to PUR foams.
