Molar Insulation Bricks
They are excellent insulation bricks with high strength and low density.
• High strength,
• Low heat capacity,
• Low thermal expansion.
Skamol Molar insulation bricks contain various properties of thermal conductivity, mechanical strength density. Maximum operating temperature is 900-1000°C. Each molar insulation brick is manufactured with the appropriate mixture of diatoms and plastic clay raw materials. Skamol Molar insulation bricks are characterized with excellent insulation properties, high strength, low weight and increased temperature. Their thermal shock resistance is high due to low thermal expansion and contraction factor. They have low permeability against gases and resistance to weak acids. SKAMOL Molar insulation bricks are used as back-up insulation in the industrial furnace refractory bricks behind the main operation.
