Versatile applications
Foundry, automotive, furnace construction, gasketing, glass processing and investment casting.
PRODUCT TYPE
High-temperature fibre paper made from biosoluble alkaline earth silicate (AES) fibre is a thin, flexible insulation material for applications with limited installation space. Superwool® papers are manufactured without binders, are inorganic and produce neither smoke nor fumes when exposed to heat. They are suitable for gaskets, expansion joints, heat shields and as separating layers in foundry applications.
MATERIAL
Alkaline earth silicate fibre (AES) consists of amorphous fibres produced by melting and rapidly solidifying a combination of silicon dioxide (SiO₂) and calcium oxide (CaO) with magnesium oxide (MgO). The XTRA variant is based on an aluminium silicate–potassium oxide chemistry with a zirconium oxide content for increased temperature resistance.
Morgan Advanced Materials
Morgan's development of low biopersistence fibres has led to a revolution in the use of fibres for high-temperature insulation applications over the past 20 years. The patented Superwool® products are manufactured using ISO 9002-certified processes from alkaline earth silicate (AES) composition fibres uniquely engineered to deliver benefits in high-temperature insulation applications.

Superwool® papers are thin, flexible high-temperature insulation sheets made from biosoluble alkaline earth silicate (AES) fibre. They are manufactured without binders and produce neither smoke nor fumes when exposed to heat. All three variants (Prime, Plus, XTRA) are exonerated under Note Q of EU Regulation EC/1272/2008 (CLP) and are therefore not classified as carcinogenic.
The papers are designed for applications with limited installation space where thin, formable insulation layers are required. They offer excellent thermal stability, chemical resistance and are easy to cut, punch and shape.
Applications
- Molten non-ferrous metal contact (aluminium casting)
- Automotive heat shields
- Investment casting mould wrapping
- Gasketing and expansion joints for furnaces, kilns, boilers
- Glass separators
- Ingot mould liners
- Thermal insulation in confined spaces
Frequently Asked Questions (FAQ)
What is Superwool® Paper?
Superwool® Paper is a thin, flexible high-temperature insulation material made from biosoluble alkaline earth silicate (AES) fibre. It is manufactured without binders and produces neither smoke nor fumes when exposed to heat. Morgan Advanced Materials offers three variants: Prime (1300°C), Plus (1200°C) and XTRA (1450°C).
Which chemistry is right for which application?
Superwool® Plus Paper (1200°C) is suited for gaskets, expansion joints and boiler construction. Prime Paper (1300°C) covers foundry applications and automotive heat shields. XTRA Paper (1450°C), which contains zirconium oxide, is designed for high-temperature furnace construction and investment casting.
What are the typical applications for Superwool® Paper?
Typical applications include molten non-ferrous metal contact (aluminium casting), automotive heat shields, investment casting mould wrapping, gasketing and expansion joints for furnaces and boilers, glass separators, and thermal insulation in confined spaces.
What does biosoluble mean for Superwool®?
Biosoluble means the fibres can be broken down in the human body. All Superwool® variants are exonerated under Note Q of EU Regulation EC/1272/2008 (CLP) and are therefore not classified as carcinogenic. No respirable crystalline silica is formed.
What densities and dimensions are available?
Superwool® Plus Paper is available in densities of 180–250 kg/m³, while XTRA Paper has a density of approx. 190 kg/m³. Available thicknesses and dimensions vary by variant — contact us for your specific requirements.
