JM23 Firebrick whisher tick powder lightweight mullite insulation brick
Mullite Insulation Brick Introduction:
The product is sintered under high temperature with high-purity raw materials and advanced production technologies. Featured by high strength and high-temperature resistance as well as thermal shock resistance, it is widely used in the lining of medium-high temperature kilns.
Mullite Insulation Brick Advantage:
1. Low thermal conductivity
2. High cold crushing strength
3. Perfect Energy saving
4. Stable volume
5. Excellent heat insulation
6. High intensity for pressure
7. Good thermal shock stability
Mullite Insulation Brick Application:
High temperature mullite insulation bricks can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy.

Kamtai produces a comprehensive range of Fire clay brick consisting of 30-55% Alumina all of which exhibit excellent strength. For more arduous environments we offer a hand fired "super duty" Fire clay brick with a very high mechanical strength.
Typically our firebrick range is based upon flint clay giving it both a low iron and low alkali characteristic. Resistance to thermal shock, abrasion, chemical attack and reducing atmospheres are just some of the key criteria determining choice of product within each application. a wide range of sizes are held in stock.
Refractory briks are packed in wooden pallets, with water-proof cover, and tightened with plastic/steel bandages.
