HEAT-INSULATING REFRACTORY BATTING
Heat-insulating refractory batting is made of a mullite-siliceous fiber, produced by melting of pure aluminum and silicon oxides in electric furnace with fiber formation by the blowing method. An inorganic binding agent is added to batting with its subsequent thermal strengthening to impart strength and elasticity to the material.
Zirconium or chrome oxides are introduced into fiber composition to increase the batting application temperature.
Roll batting is a flexible and stronger insulating material. It can be cut with a knife and cut out to the required shapes, bonded to a rigid substrate with inorganic glues and fixed with mechanical fastenings made of heatproof alloys or ceramics.
