Ceramic fibre boards are manufactured from inorganic amorphous glass fibre that is designed to operate at temperatures up to +1260°C. This refractory material is asbestos free, lightweight and offers excellent resistance to chemicals, gasses and thermal shock. Ceramic fibre boards are easy to install and provide low thermal conductivity and heat storage. They also provide excellent resistance to h
Product Description
Properties of Ceramic Fiber Wool:
Ceramic fiber wool is a type of insulation material that is made from a blend of ceramic fibers and binders. The material is lightweight, durable, and has excellent insulating properties. The fibers used in the material are made from alumina-silica, which is a combination of aluminum oxide and silicon dioxide.
One of the most significant advantages of ceramic fiber wool is its ability to withstand high temperatures. The material can withstand temperatures of up to 1,300 °C without degrading or losing its insulating properties. This makes it an ideal choice for applications where high temperatures are a concern.
Ceramic fiber wool is also resistant to chemical attack and can withstand exposure to most chemicals, acids, and alkalis. It is also resistant to thermal shock, which means that it can withstand rapid changes in temperature without cracking or breaking.
