Product description of JM30 mullite insulating bricks
Mullite insulating bricks JM30 are a good refractory raw material, category in which aluminum silicates are produced at high temperatures. Mullite allows the production of various types of intermediate insulating bricks, which have already been successfully used in various industrial sectors.
Features of JM30 mullite insulating bricks
Refractory insulation brick JM30 is a new type of energy-saving refractive that has direct contact with flames and has characteristics such as high temperature resistance, stability in case of strong thermal shocks, high resistance and poor thermal conductivity.
