Product Details
Plastic refractory castable are made of high quality refractory aggregate mixed and kneaded with a combination of clay, water and other chemical binder, and they can be easily formed and installed to suit any specific shape.In the case of plastic refractories, they stay soft and can be freely shaped and reshaped at will, which can be valuable in the case of an emergency cases. In addition to this, they are used for walls, ceilings, bottoms or burner blocks of diverse furnaces.
