HIGH DENSITY CALCIUM SILICATE INSULATION BOARD

With density range 850-950kg/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.

CHARACTERISTIC:

◎    Low thermal conductivity, low heat losses at higher temperature.

◎    Non wetted by molten aluminium .

◎    Resistance to thermal shock.

◎    Excellent machining.

◎    Asbestos-free.

APPLICATION :

◎    Ladle Insulation Liner clamping fixture of car glass.

◎    Dip tubes

◎    Pouring spouts

◎    Hot-top rings

◎    Stopper pins

◎    End dams

◎    Floats

◎    Launders.
