Project description

Numerous historic valuable buildings and cultural artefacts from the last century have components made of transparent acrylics. Especially cultural objects outdoors are affected by increased UV-light, pollutants, soot, graffiti and vandalism, which damage their once transparent appearance and their substance. Instead of removing and replacing their original substance, historical acrylic components belonging to valuable cultural heritage should be maintained on a regular basis to prolong their lifespan.

In contrast to the middle of the last century, when synthetic polymers were considered to be efficient, versatile and everlasting, plastics are now regarded as being problematic materials. The multitude of designs in postwar cultural heritage was enabled largely through plastic products, which are indispensable in their original substance. The plastic products represent and transmit historical values. Furthermore, they carry information about historical recipes and production techniques. For synthetic polymers like acrylics, there are as yet no approved and verified maintenance and sustainable methods as there are for more common historical materials in built heritage. A different view on plastics, not as disposable products, but as a material and cultural resource that should and can be preserved, is the basis for preserving the material heritage of modernity.
