Einar® coating additives for expandable polystyrene (EPS) • Einar® 501 is a fine-powdered high quality, sustainable anti-stat • Einar® 511 is a fine powdered cooling time enhancer • Einar® coating additives are free-flowing powders with high coating efficiency Application background . Expandable polystyrene (EPS) is a lightweight, strong product that offers very good thermal insulation, making it ideal for the packaging and construction industry. It is used for a very diverse range of applications including trays, cups plates and fish boxes. EPS will need a basic formulation of coating additives in order to function efficiently during handling and processing of EPS beads in to final moulded products. GMS, GTS and metal stearates such as Zn- or Mg-stearate make up a very common combination of coating additives that secures anti-stat protection, improvement of flow properties during processing and pre-expansion and secures better and faster cooling of moulded parts.
