Superwool Plus Paper
Note : Pre-order item
Description :
Superwool Paper is a unique family of paper products manufactured using our patented Superwool low biopersistent fibre in the non-woven matrix. Special organic binders and fillers are used for giving them strength and distinct physical properties suitable for a varying range of applications. Superwool Plus Papers offer excellent thermal performance over a wide temperature range.
Superwool Plus Papers are an alternative to traditional solutions due to their unmatched properties of high refractoriness, elevated temperature capabilities and lower thermal conductivity. These papers have excellent non-wetting characteristics for the applications requiring direct contact with molten aluminium.
Superwool provides stability and resistance to chemical attacks. 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.

Environmental & Health Safety :-
Superwool low biopersistent fibres 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). Superwool low biopersistent fibre products are therefore exonerated from classification and labelling as hazardous in Europe.
