NON-RCF Insulation Blanket Type Z-MAG-B
has excellent chemical stability and is unaffected by most chemicals except hydrofluoric
and phosphoric acids and concentrated alkalis. If wet by water or steam, thermal and
physical properties remain unaffected after drying. It provides superior resistance to
attack from molten aluminum alloys at high temperatures.
