Superwool® Plus and Prime Papers

Low biopersistent fibre papers with excellent thermal performance, non-wetting to molten aluminium, and chemical stability.

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 and Superwool HT Papers offer excellent thermal performance over a vide temperature range.

Superwool Plus and Superwool HT 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.
