JM23 JM26 JM28 insulating fire brick/ IFB/mullite insulation fire brick

JM23 insulation brick is color of white insulating fire brick, with light Weight, based on aluminum silicate refractory materials.
It’s made from high-purity refractory clays with graduated additions of alumina for applying in higher temperature working conditions. JM23 insulation brick with different bulk density from 0.6g/cm3~1.2g/cm3.

Mullite insulating fire brick are carefully graded organic fillers burn out during firing to give a uniform, controlled pore structure with good performance on insulation values.

Classification by refractoriness: JM23 JM26 JM28 JM30 JM32  (Gr23 Gr26 Gr28 Gr30)

SIJIHUO REFRACTORY producing lightweight, mullite insulating firebrick has successfully helped the final users to reduce their operating costs by saving energy during furnace operating.

SIJIHUO REFRACTORY produce extensive range of insulating firebrick products, and provide solutions in thermal engineering and furnace design.

1. Low levels of iron and other impurities, and good chemical corrosion resistance
2. High mechanical intensity, with Long service life
3. High refractoriness, can contact with the flame directly, suitable for various atmosphere
4. Superb performance ofinsulating values at different temperatures
5. Low creep rare at high temperature,good thermal shock stability

Light Weight Mullite Insulation Brick can be directly as a fire-resistant lining or insulation layer, but also in the high-temperature furnace burner brackets, burner fixed brick and light burner brick replacement products. 

It can be widely used in hot face refractory linings or as back-up insulation materials.  Such as high temperature processing of metals, petrochemicals and ceramics.
