HIGH DENSITY CALCIUM SILICATE INSULATION BOARD

 
    With density range 750--900kgs/m3 ,high density calcium silicate insulation board is developed for the non-ferrous industry used for feeding ,casting and molding of  molten aluminum and other non-ferrous metals, also can be used for clamping fixture of glass industry . In addition to its insulation, its characteristic of non-stick aluminum exerts a large. Superior strength and good processability makes it the preferred material for precision CNC machined parts and complex components. There are two types, namely, glass fiber reinforced and carbon fiber reinforced.
