    SILICA BOARD & H.T.B is an insulating materials for heat insulation.
    it has outstanding heat-resisting, water-resisting, compression strength and is crashworthy.
    So it is light and transformed easily as necessary that it is used in various kinds of fire-proof equipment.
    According to crystal structure, Silica' workable temperature is – 650℃ and HTB' is – 1000℃.
