INSWOOL MOLDABLE is a 2300°F ceramic fiber, putty-like consistency material, used for linings up to three inches thick, to pack large voids, or even fill thin cracks. It can be troweled or hand packed into place.
INSWOOL MOLDABLE is light weight, with very low thermal conductivity, and therefore a good insulator, yet it develops a strong hot face surface to withstand physical abuse and high air velocities as compared to conventional ceramic fiber products. It is also used as a high temperature gasket material, and as a general purpose patching product. Its ability to compress makes INSWOOL MOLDABLE an excellent material for expansion joints and for filling contraction cracks. It is also an ideal material to fill ceramic cuplock anchors for ceramic fiber blanket linings, and can be used in contact with molten aluminum.
INSWOOL MOLDABLE has excellent thermal shock resistance, and can be dried or put into service immediately with no pre-heat required, with the exception of direct molten metal contact. Then the INSWOOL MOLDABLE should first be thoroughly dried, and fired, to remove all mechanical water the entire depth of the material, to avoid dangerous steam explosion.
