Fire Clay Insulation Castable

Jun 30, 2021

Good workability, strong cohesion, initial setting time and construction can be a long time, fast strength growth, strong impermeability, no acidification, easy to ensure that the masonry plaster full and dense, can significantly improve the chimney liner air tightness, integrity and anti-corrosion ability. It is an ideal cementing material for high chimneys, high temperature flue and duct lining. It can also be used in acid tank and other acid resistant parts in petroleum, chemical, nonferrous metallurgy and so on.

Application of Clay Insulation Castable
