102.jpg (2192 bytes)  NON-RCF Insulation Blanket Type Z-MAG-B

GENERAL INFORMATIONasb23th.JPG (5434 bytes)
Insulation Blanket Type Z-MAG-B consists of soluble NON RCF fiber formed into a mechanically needled flexible blanket. The fibers in it are soluble in body fluids and offer users a "safer" alternative to refractory ceramic fiber blankets. It meets European regulatory requirements (Directive 97/69/EC).
In many applications it can be used as a direct substitute for traditional RCF containing insulating blankets. Z-MAG-B blanket finds use in applications with temperatures to 1260 C (2300 F) and is available in a variety of thickness' and densities. It has good handle-ability and strength plus low shot content and is easily cut.

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.
Z-MAG-B blanket ideal for use  as furnace insulation in sintering, heat treating and chemical thermal process systems. It can be layered between rigid insulation, wrapped around process piping or fabricated into folded modules. It is also useful as insulation packing in furnace spaces, around furnace sight tubes & ports and fill in expansion joints and masonry cracks.
