SBD Biosoluble Fiber Thermal Insulation Board

SBD Biosoluble Fiber Thermal Insulation Board
Product Details

Biosoluble fiber board

Firewheel Ref.No. SBD Biosoluble fiber board are made from soluble fibre and a small amount of organic binder. Due to the high fibre content, Soluble fiber board are strong, light weight and thermal shock resistant. Thicknesses over 50mm are obtained by bonding resistance two thinner sheets. It features Waterproof, Resistant to thermal shock, Low thermal conductivity, Precise geometry and close tolerances, Homogeneous structure, easy for machining, Non-brittle, High fibre content, Lightweight, low heat storage.

Refractory lining for industrial furnaces in walls, roofs, doors, stacks, etc.
Combustion chamber liners,boilers and heaters
Back-up insulation for brick and monolithic refractories
Transfer of molten aluminum and other nonferrous metals
Expansion joint boards
Barrier against flame or heat
Hot face layer for high velocity or abrasive furnace atmosphere
