Insulating Castables,Low Cement Castables,Insulating Castable Refractories,Low Cement Refractories

Insulating Castables (Regular & Low Iron)
We provide range of insulating castables with speciality materials and low densities. These insulating castable refractories are used as either a back up lining or for hot face work. They are of low to medium strength making them not suitable to abrasion or particle attack.
