Insulfrax® Mouldable are high-performance insulation materials composed of Insulfrax alkaline earth silicate wool dispersed in high-temperature binders. Upon drying, these mastics form a strong insulating structure with low thermal conductivity. They can be caulked, trowelled, pumped, or moulded quickly and easily, making them ideal for filling, sealing, repair, and general packing applications in industrial furnaces and process equipment.
Engineered for low thermal conductivity, resistance to thermal shock, low shrinkage, and excellent adhesion, Insulfrax Mouldable provides reliable performance while simplifying installation and maintenance processes.
Insulfrax Mastics offer durable, energy-efficient insulation solutions for high-temperature applications.
