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.

Super Hybond plastic refractories are high-strength, super-duty plastics with excellent resistance to thermal shock from rapid heating or cooling furnace conditions. They are air and heat setting materials with no minimum time before firing. Super Hybond is available in a range of alumina compositions from 44% to 91%, and they are phosphorous free for applications where phosphorous contamination is critical. Super Hybond has excellent CO resistance and higher strengths to withstand mechanical abuse than conventional heat-setting plastics.
