HIGHH DENSITY CALCIUM SILICATE INSULATION BOARD

With density range 800--1000kgs/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. 

A  Characteristic

   Special carbon fibre makes it unparalleled strength and low shrinkage

Low thermal conductivity ,low heat losses at higher temperature

Non wetted by molten aluminium

Resistance to thermal shock

Excellent machining

Asbestos-free

B   Application 

Furnace inside lining

Continuous caster tips

Transition plate

Baffle plates

Gasket,stopper

  Through liners

   Floats,Spouts

        Head box
