With density range 750 – 900 kgs/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 with its characteristic of non-stick aluminum.
It also can be used for clamping fixture of glass industry. 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.
