HIGH DENSITY CALCIUM SILICATE INSULATION BOARD
HIGH DENSITY CALCIUM SILICATE INSULATION BOARD

Product review

Description

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.
