GM 32

GM 30S

GMK Anorthite Insulating Firebrick

GM 32 offers an affordable yet effective alternative to bubble alumina bricks for high-temperature applications or when a high alumina content is crucial, providing both quality and cost-efficiency.

GMK Anorthite Insulating Firebrick

GMK Anorthite Insulating Firebricks, aligning with international standards, are high-efficiency, eco-friendly insulating products. They are crafted by mixing clay and plaster, which upon firing, forms anorthite, reducing the brick's weight by about 70% and resulting in low thermal conductivity and high porosity. This process makes them ideal for energy-saving applications where insulation is key.

GRM Air Setting Refractory Mortar

GMK Anorthite Insulating Firebrick

GRM Air Setting Refractory Mortar

GRM refractory mortar is crafted from a blend of select refractory powders and binding agents, tailored to match various insulating firebricks or refractory bricks. This air-setting mortar, conveniently packaged in barrels, dries naturally and offers exceptional bonding strength, creating durable brick joints. GRM mortar is ideal for joining insulating firebricks, uniquely shaped bricks, or alumina bricks, ensuring a robust and reliable assembly in high-temperature settings.

Bubble Alumina Brick

GMK Anorthite Insulating Firebrick

GRM Air Setting Refractory Mortar

Bubble Alumina Bricks, known for their lightweight and high-temperature resistance, enhance furnace efficiency by retaining heat and reducing production times. They are ideal for various kilns and furnaces due to their low thermal conductivity, strength, and minimal thermal expansion.

Corundum Brick
