In 1949, the scientist Dr. Fritz Stastny, a chemist at BASF, discovered expanded polystyrene. EPS. When this raw material, in bead form, is combined with steam, it swells to up to 40 times its original size. It can subsequently be reworked in moulds.
Therefore, airpop® is composed mostly of air. 98% air to be precise. For a long time, EPS was known in Europe under different names, such as polystyrene or “Styropor” among others. This material now has a single new name: airpop® engineered air.
