JM30 Insulation Brick Description
JM30 insulation firebrick is made from high purity refractory clays with gradually increasing aluminum oxide content and are carefully saturated with organic filling, which then burns out during the production process, resulting in a homogeneous, controlled porous structure. To achieve required tolerance, all six walls of each brick are mechanically processed.
Properties of JM30 Insulation Brick
- Excellent compression strength,
- Excellent heat stability,
- Low thermal conductivity,
- Low heat storage,
- Thermal shock stability with high strength.
