Altra® polycrystalline wool

Excellent up to 1650°C

 

ALTRA® is a polycrystalline wool of high purity with excellent thermal and mechanical properties, which is produced in a sol-gel process without the use of binders. As a result, the ALTRA® high temperature insulation wool offers virtually infinite thermal shock resistance and is thus excellently suited for periodically operated systems. RATH is the only supplier of polycrystalline wool in three grades with alumina contents of 72%, 80%, and 97%. The products are particularly suitable for use in the high-temperature field up to 1650 °C and offer a wide range of application possibilities.
