Cerak Wool

Cerakwool is

Spun Ceramic Fiber, a high-temperature fire-resistant insulation material manufactured by the state-of-the-art Spinning method of KCC.
KCC, which was the first to develop ceramic fiber in Korea, has developed and produced Spun Fiber which is superior in quality than blown fiber by conventional blowing method. Spun Fiber has a longer fiber length than Blown Fiber, so it has excellent tensile strength and various physical properties.

  • Power Plant

    Cerak Wool is an essential material for improving the thermal efficiency of facilities exposed to high temperatures such as turbines, boilers and HRSG of combined cycle power plant that are main equipment of power plants.

  • Steel/steelmaking Industry

    Cerak Wool is an insulation material that can withstand ultra-high temperatures and areas directly exposed to flames in steel production and heat treatment facilities.

  • Petrochemical Industry

    Cerak Wool is an insulation material with strong chemical resistance at high temperatures. It is mainly applied by petrochemical facilities to the inner parts of the heaters to stabilize the production of high value added products.

Product Detail

Features of Cerak Wool

Physical Stability - New Bio

New Bio is an environmentally friendly, biodegradable, super-high temperature fireproofing material that dissolves and emits rapidly in the body even when inhaled.
image

High-Temperature Stability

It has excellent product stability at high temperatures.
image

Excellent Thermal Conductivity

With very low thermal conductivity at high temperatures, Cerak Wool exerts excellent insulation effects.
image

Low Heat Capacity

Cerak Wool has lower density and less accumulated heat than firebricks, thus, reducing heat loss caused by the accumulation of heat in the furnace.

Workability, Flexibility

Cerak Wool is light and flexible compared to conventional fireproof materials, enabling easy installation to any part.
