Since the middle of the last century, at the latest, life without plastics has no longer been conceivable. Polymer materials have now become an indispensable part of mobility, medicine, electrical engineering, telecommunications, packaging, construction and home life, even sport and leisure. And not even one percent of global crude oil and natural gas production is used for the world?s production of polyethylene. In addition, there is scarcely another plastic with such long assured functionality even under continuous exposure to load (100 years).
