HIGH DENSITY CALCIUM SILICATE INSULATION BOARD
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.
