Wedge India Ceramic Millboards are premium high-temperature resistant insulation sheets designed for furnace backup insulation, thermal gasketing, and fire protection applications. Manufactured from refractory mineral fibers such as calcium silicate, wollastonite, and ceramic fibers bonded with high-temperature clays, these asbestos-free millboards combine excellent thermal resistance, mechanical strength, and electrical insulation properties.
 
Key Features & Benefits
High Temperature Resistance: Withstands 1000 °C to 1260 °C continuous service temperatures.
Low Thermal Conductivity: Ensures maximum energy savings in furnaces and industrial kilns.
High Compressive & Flexural Strength: Provides durable sealing and gasketing performance.
Electrical Resistance: Reliable insulation even under high-temperature electrical load.
Fire & Heat Shielding: Ideal for fire-resistant doors, lifts, and safe enclosures.
Easy to Cut & Punch: Can be fabricated into gaskets, seals, washers, and expansion joints.
Versatile Form: Available as flat sheets, gaskets, and molded pipe insulation.
 
Applications
Ceramic Millboard is widely used across steel, cement, glass, petrochemical, and power industries, including:
Furnace & Kiln Insulation – backup insulation for dryers, ovens, lime & cement kilns.
High Temperature Gaskets & Seals – boiler doors, centrifugal castings, pipe insulation.
Expansion Joints & Fire Barriers – refractory expansion joints, electrical & appliance insulation.
Industrial Burners & Rollers – insulation for burners, glass rollers, and mandrel washers.
Fire Resistant Construction – fire doors, lifts, cupboards, safes, and high-rise fire protection systems.
