Fire-proof glue
The range 300-450kgs/m3 0f 1000 centi—degree Calcium Silicate Insulation Board has been developed to provide outstanding service in demanding fire—proof application such as industrial chimney and flue part contact fire directly.It also can bear load and support diiferent from refractory backup insulation.Uses include fire—rated enclosures around structural steel,tanks,equipment,fire—rated walls and fire—proof doors.Double sanded surface finishing give a precise specification.Test report made in European authorized lab are available.
