Where can i buy insulation refractory castable? And what is insulation refractory castable?
Henan is the most famous refractory raw material basis in China. SIJIHUO REFRACTORY has manufactured unshaped refractories for more than 20years. We can help to solve your problems of refractory castable.
Insulation castable is the widely used thermal insulation refractory material for industrial furnace insulation linings. It's made of lightweight refractory aggregates and fine powder, binders, and additives. Refractory aggregate varies including high alumina, porous clay, hollow ball, expanded perlite, and mullite materials, etc, which decided the different insulation castable chemical and physical properties.
This kind of insulation castable is suitable for insulation linings of cement rotary kiln.

As per different furnace lining design, and client’s demand on insulation castable specification should also be adjusted. Bulk density varies from 0.5~1.8g/cm3, thermal conductivity will be changed accordingly. Any professional suggestions on your furnace lining projects, please contact SIJIHUO REFRACTORY for more recommendations.
