Note: This is a variation of Plastic Refractories.

Plastic refractories are supplied in an unfired and formable condition. They are installed by hand or with the use of a pneumatic hammer to form the refractory mass. These products are used both for original installations and for patching. Plastic refractories can be used in many varied applications and locations because they arcell namessentially formed by the installer to fit the specific use area. Refractory plastics can be used to patch or repair worn refractory areas whether they were originally brick castable or plastic. For the best results, the worn refractory should be removed back to a sound surface, removing loose material and preferably providing V-shape surfaces that will allow good bonding of the patch to the original refractory. A bonding mortar coating aids in achieving a lasting patch with good adherence.

Additional Information

GREENPAK-85-P is a high alumina, phosphate bonded plastic with excellent strength, outstanding slag resistance, good workability, and volume stability at high temperatures. It demonstrates good resistance to alkali attack. typical applications are incinerator linings including afterburners, aluminum holding furnace sidewalls and ramps, steel mill maintenance linings, ladle linings holding iron, carbon steel, aluminum, brass, bronze, and zinc, burner blocks, and soaking pit slaglines.
