    REFRACTORY & HIGH-TEMP INSULATION

    Fiberfrax® LDS Moldable – High-Performance Ceramic Insulation
    Refractory Repair & Castable Solution for 1260°C Applications

    Fiberfrax® LDS Moldable is a highly adaptable ceramic fibre insulation compound designed for casting, patching, coating, and lining in extreme temperature environments. Its sticky, water-based binder forms a strong bond with refractory and metal surfaces, drying into a durable, low-conductivity barrier that withstands up to 1260°C.

    Perfect for both structural and maintenance insulation, LDS Moldable offers excellent thermal resistance, minimal shrinkage, and a hardened finish—ideal for use across high-heat industrial applications and refractory repair.

    Key Benefits:

    • High Temperature Rating: Withstands continuous exposure up to 1260°C
    • Excellent Bonding: Strong adhesion to metal linings and refractory surfaces
    • Low Shrinkage: Maintains form and insulation under high heat
    • Hard Set Finish: Air-dries to a tough, resilient surface

    Common Applications:

    • Hot and cold repairs of refractory cracks and insulation voids
    • Aluminium trough linings and non-ferrous metal equipment
    • Burner block sealing and welding protection
    • High-temperature turbine and pipe coating
    • Refractory anchor insulation and boiler repair

    Frequently used alongside Fiberfrax® QF180 Coating for surface sealing or with Fiberfrax® XJ1 Pumpable where injection-style application is needed.
