Thermal Ceramics JM30HA Insulating Firebrick 1650 °C
- Brand: ThermalCeramics
- Product Code: JM30HA
Thermal Ceramics JM30HA is a high-alumina lightweight insulating firebrick with a classification temperature of 1650 °C and a bulk density of 1250 kg/m³. It is used as hot-face lining in high-temperature furnaces or as back-up insulation behind dense refractories; its low heat storage reduces furnace heat-up time and energy consumption.
