SBLK Biosoluble Fiber Thermal Insulation Blanket

SBLK Biosoluble Fiber Thermal Insulation Blanket
Product Details

Bio-soluble fiber blanket

Firewheel Ref.No. SBLK96/128 Biosoluble fiber blanket is a body soluble fibre that utilies a unique spinning technology to create a special fibre with superior thermal and mechanical properties. This special fibre is made from a blend of calcium, silica and magnesium which give fiber the ability to support continuous temperatures up to 1000℃. It features Low thermal conductivity, Low heat storage, High tensile strength, Thermal shock resistance, Light weight, excellent corrosion resistance.

Typical applications:
Aluminium homogenizing furnace linings
Back-up insulation for dense refractory
Annealing furnace linings
Stress reliecing blankets
Heat treatment furnace linings
Crude heater linings
Co-generation duct linings
Reusable insulation pads
Expansion joints.
