We offer you the entire range of materials for high temperature insulation. These can be supplied as semi-finished products or cut to size, stamped products, milled products or components. We can also supply you with the corresponding high-temperature adhesives and anchoring systems. We are happy to support or take over the assembly of the products for you – according to your wishes and possibilities.

Information / Qualities

AES – The AES qualities are alkaline earth silicate wool. The AES wool consists of a combination of CaO, MgO and SiO2. These materials have a so-called biosolubility (correct: materials with a low bio-resistance) and are not classified.

PAS – The PAS qualities are potassium aluminium silicate wool (potassium aluminosilicates). The PAS wools consist of a combination of K2O, Al2O3 and SiO2. These materials have a so-called biosolubility (correct: materials with a low bio-resistance) and are not classified.

RCF – The RCF qualities are aluminium silicate wool (refractory ceramic fiber). The RCF wools consist of a combination of Al2O3, SiO2 and possibly ZrO2. The International Agency for Research on Cancer (IARC) confirmed again in 2001 that Group 2B (“potentially carcinogenic to humans”) remains the appropriate classification for RCF high temperature wool.

PCW – The PCW grades are aluminium silicate wool with an Al2Ocontent > 72% (up to 99% Al2Odepending on the grade) These qualities are used either at operating temperatures > 1300 °C and for special chemical requirements (e.g. in hydrogen containing atmospheres). The PCW qualities are not classified, despite a similar chemical composition as RCF fibres.

Classification temperature

The classification temperature is defined as a temperature at which, after 24 hours of exposure to a neutral atmosphere, the shrinkage of plates and moulded parts is a maximum of 2% and that of mats and papers a maximum of 4%. However, the shrinkage is not yet complete.
This means that the application temperature of the products, in practice and in a neutral atmosphere, should be 100 °C to 200 °C below the classification temperature. Polycrystalline wool products can generally be used up to the classification temperature.
