Soluble ceramic fibre blanket Low thermal conductivity. Low heat storage. High tensile strength.Thermal shock resistence.Low weight.Corrosion resistance It is a body soluble fibre that utilise a unique spinning technology to create a special fibre with superior thermal and mechnical properties.This special fibre is made from a blend of calcium, silica and magnesium which give fibre the ability to support continuous temperatures up to 1000 centigrades.
