Product Description Product DescriptionThe JM26 / JM32 Lightweight Insulating Fire Brick is a high-quality alumina-silicate refractory brick designed for industrial furnaces, kilns, and boilers that require excellent thermal insulation and energy saving performance.Made from high-purity raw materials under precise firing control, these bricks have low density, low thermal conductivity, and excellent thermal shock resistance, ensuring reliable insulation at temperatures up to 1350-1450°C.They are ideal for use as back-up insulation lining in high-temperature equipment, helping to reduce heat loss, improve furnace efficiency, and extend lining life.FeaturesHigh Temperature Resistance - Suitable for continuous operation at up to 1450°C (JM32).Lightweight and Energy Saving - Density only 0.6-1.0 g/cm3, reducing furnace wall load.Low Thermal Conductivity - Outstanding insulation efficiency with minimal heat loss.Excellent Thermal Shock Resistance - Can withstand rapid temperature changes without cracking.High Mechanical Strength and Dimensional Accuracy - Easy installation and long service life.Environmentally Friendly - Asbestos-free and manufactured under ISO-certified processes. ApplicationsIndustrial Furnaces and Kilns - Used in hot-face and back-up insulation linings.Boilers and Heat Treatment Equipment - Energy-saving refractory lining material.Ceramic Kilns and Glass Furnaces - As insulation layer under working linings.Petrochemical and Metallurgy Industry - For reactor insulation and hot surface protection.Laboratory and Pilot Furnaces - Lightweight structure with stable performance.BrandPropertiesJM-23LDJM-23JM-26JM-28JM-30JM-32 Classification temperature (oC)130013001400150015501600 Bulk Density (g/cm3)0.550.60.80.91.01.1 Cold Crushing Strength (MPa)1.01.21.82.53.33.5 Modulus of rupture (MPa)1.01.01.72.33.13.2 (CToCX24h) Permanent Linear Change (%) -0.40.60.60.80.91.01@ 1,100oC Thermal Linear Expansion (%) 0.500.500.520.520.530.7Thermal conductivity (W/m.k)350oC0.140.180.270.320.380.49400oC0.150.200.290.340.400.5600oC0.170.240.320.360.420.51 (%) Chemical Analysis Al2O3384056677377Fe2O30.8 (CaO12%)1.00.80.70.70.5Q1: What's the main difference between JM23, JM26, JM28, and JM32?A1: The higher the JM number, the higher the alumina content and service temperature.JM23 for ≤1260°C; JM26 for ≤1400°C; JM32 for ≤1600°C applications.Q2: What is the main application of JM26 and JM32 insulating bricks?A2: Mainly used for kiln, furnace, boiler, glass and ceramic industry insulation lining.Q3: Can you provide customized sizes or shapes?A3: Yes. Bricks can be produced according to customer drawings or standard refractory shapes.Q4: How do you control product quality?A4: Every batch is tested for density, porosity, and thermal conductivity before delivery.We use ISO9001-certified production and testing systems.Q5: What's the minimum order quantity and lead time?A5: MOQ is flexible (usually 1 pallet). Delivery within 15 working days after confirmation.
