Inswool Pumpable Refractory Caulking

INSWOOL PUMPABLE is a 2300°F, 10.3 oz tube ceramic fiber, putty-like consistency material, specially formulated for pumping with a caulking gun. It is usually used for pumping behind existing hot face linings for insulating purposes; however it can be used to fill small voids and thin cracks.

INSWOOL PUMPABLE is a light weight material with very low thermal conductivity, and therefore a good insulator. It dries to a firm, board-like consistency, for good sturdy integrity. Its ability to compress makes it ideal for expansion joints, and for filling contraction cracks. In addition it is used in contact with molten aluminum.

Although normally used as a backup material for hot spots, as mentioned above, when used as a hot face material, the INSWOOL PUMPABLE 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 PUMPABLE should first be thoroughly dried, and fired, to remove all mechanical water the entire depth of the material, to avoid dangerous steam explosion.
