Mouldable plastic is made by refractory aggregate,powder,binder and admixture.It has good work performance and plasticity. According to America ASTM, mouldable refractory’s plasticity index is more than 15%,castable refractory’s plasticity index is less than 15%.In China, mouldable refractory’s plasticity index is between 15%-40%.

Applications of our refractory plastic mouldable :
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 .our factory manufactures many types of plastic refractories designed for original installations and patches and for compatibility with the application conditions
Wear-resisting refractory plastic mouldable.
Features of the refractory plastic mouldable :
