    Insulating Castable Composition

    Insulating Castable is made of a certain refractory material such as alumina, adding some binder being made into powered refractory materials, so it has good liquidity, workability and adhesiveness, naturally, its initial setting time and construction operation time is long. As for the construction aspect, it was usually used by the methods of ramming, vibration, spraying and casting. During the process of construction, its strength grows fast, and with the strong resistance to permeability, light weight insulation castable ensures the density, integrity and anti-corrosion ability of the masonry.

      Insulating Castable Properties

      Insulating Castable properties and features: Light weight insulation castable has good heat preservation performance and strong integrity, so it saves energy, over 20%, than ordinary refractories. With high refractoriness and spalling resistance performance, it has long service life. Meanwhile, it can be used to repair the kiln or furnace, thus improve the service life of such thermal equipment as well, thus saves money.

      Insulating Castable has another features, such as light weight, low thermal conductivity, low bulk density, high compressive strength, and resistance to acid corrosion.
