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.

The Plastech line of plastics are high-alumina, phosphate-bonded plastic refractories with better alkali resistance than conventional heat-setting plastics. Plastech has a long shelf life of 6 months, and stable workability over time resulting in less waste. It exhibits excellent pliability and takes less time to install than competitive products. Plastech is available in soft, standard, and firm consistencies, and alumina compositions ranging from 50% to 90%. Fine grain versions are also available for applications requiring more intricate features and surface details.
