حقایق PUR: حفاظت از فوم پلی‌یورتان در هنر و طراحی

Flexible Polyurethane (PUR) foams have been used since the 1950s in textiles and furniture upholsteries, and in art and design objects that can now be found in museum collections. Composed from “short-life” consumer materials, these objects present severe conservation problems as they age. This book presents an in-depth examination of the challenges presented by PUR foams; the case studies of preservation of two works by the artist Piero Gilardi; and a manual on preparing and applying a light stabilizing system that can protect new PUR foams from degrading and restore the flexibility of old foams. 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. Zacht Polyurethaan (pur) Schuim Wordt Sinds 1950 Gebruikt Voor Het Maken Van Stoelkussens En Matrassen, In De Vulling Van Kleding En Ook, Sinds De Jaren Zestig, Voor Kunstwerken. De Met Dit Zachte Schuim Vervaardigde Kunstwerken En Designstoelen Hebben Echter Een Vrij Korte Levensduur. Pur-schuim Is Niet Gemaakt Om Lang Goed Te Blijven. Thea Van Oosten Bespreekt De Verschillende Middelen Om Lichtveroudering Tegen Te Gaan, Om Nieuw Pur-schuim Te Beschermen Tegen Verval En Om Oud Gedegradeerd Schuim Opnieuw Veerkrachtig Te Maken. Ze Kijkt Ook Naar De Mogelijke Invloed Van Deze Middelen Op Het Uiterlijk, De Flexibiliteit En De Chemische Eigenschappen Van Pur-schuim. [thea Van Oosten].
