Its main component is pure glass , produced with mixed foam agent through high temperature foaming and annealling, is a new type of inorganic thermal insulation material composed by thousands of tiny uniform hermetically closed glass cells. It does not contains asbestos , ozone depleting substances, flame resistant additives or binder or other volatile substances.

It's commonly applied in insulation projects such as: tank and tank base, pipeline, vessel, equipment, cryogenic ship, etc, for petroleum, chemical, refrigeration, underground projects, shipbuilding, national defense and residential construction industries. It can can be applied in severe environment like: low & cryorgenic / hot temperature, underground, outdoors, flammable, wet, and chemical etc.
