Polycrystalline Alumina Fiber Blanket is manufactured using the “Sol-Gel” colloidal method to be a micro-crystalline mullite-based high temperature refractory fiber, by a high temperature calcination process. It is made from alumina fiber with double punching and it doesn´t contains additives or other ingredients.
Features:
l  Excellent stability at high temperature.
l  Slight contraction due to heating.
l  Low shot content, remarkable insulating and refractory performance.
l  Good thermal reflection capacity.
l  Low heat storage, low thermal conductivity.
l  Uniform distribution of the diameter of the fiber, high tensile strength.
l  Good flexibility at high temperatures, excellent thermal shock and mechanical vibration resistance.
l  Chemical stability, high resistance to corrosion.
Application:
l  Furnace hot face lining in high-temperature industries
l  Backup insulation
l  Burner block warps
l  Expansion joints
l  Gaskets in furnaces
