EST™ D Paper Product Data Sheet Product Description EST D Paper is surface treated on one side and developed for pack level protection in lithium ion battery packs. EST D Paper is uniquely manufactured from Superwool® bulk fibres and organic binders. The coating to the EST D Paper allows for dust suppression into the pack. Superwool fibres provide stability and resistance to chemical attack. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis (i.e. NaOH, KOH). Superwool is unaffected by incidental spills of oil or water. Thermal and physical properties are restored after drying. Dust suppressant coating Pack level protection of Lithium Ion batteries Environmental & Health Safety Superwool low biopersistent fibres manufactured by Morgan Advanced Materials are not classified as carcinogenic by IARC or under any national regulations on a global basis. They have no requirements for warning labels under GHS (Globally Harmonised System for the classification and labelling of chemicals). In Europe, Superwool fibres meet the requirements specified under Note Q of European Regulation EC/1272/2008 (on Classification, Labelling and Packaging of substances and mixtures). All Morgan Advanced Materials Superwool low biopersistent fibre products are therefore exonerated from classification and labelling as hazardous in Europe.
