In 2024, expandable polystyrene (EPS) celebrates its anniversary: the 75th anniversary of its (accidental) discovery. A lot has happened since then and EPS is used in so many areas of our daily lives that it has become indispensable. Foodstuffs such as vegetables and fish are packaged in it to keep them cool, transportable and fresh for longer. Electronics, household appliances and furniture are wrapped in it for transportation to their destination to protect them from damage. And in the construction sector, EPS is used on building facades to provide efficient thermal insulation. This is just a small selection of the possible uses. Special fields of application, such as cool boxes for vaccines (see article: How SOFTENOL® is helping to contain the pandemic), round off the versatility of this material.
