What is EPS?
Back in 1949 Dr. Fritz Stastny, a scientist working at BASF in Germany, invented expanding polystyrene, in short: EPS. When the pearl-shaped raw material is brought into contact with steam it expands to around 40 times its original size. It can then be moulded during subsequent processing. This means that EPS® or airpop, as it also called, consists largely of air. 98 percent to be exact. EPS has been known under a variety of names over the years. For example, polystyrene and foam packaging.
