Cellular glass is a new inorganic thermal insulating material with a structure of equally closed cells. The composition is glass, added with foaming agent. It’s foamed by high temperature in foaming oven, and then cooled down in cooling oven. It well reserves the chemical stability of inorganic glass. DEC series cellular glass has the following features: low density, low thermal conductivity, vapor impermeability, no water absorption, incombustibility, protection from mould and rat eating, high mechanical strength but easy to cut and able to bear all kinds of chemical erosions except the hydrofluoric acid. DEC series cellular glass quality meets ASTM standard.
Cellular glass, nontoxic in itself, has stable chemical properties and good thermal insulating performance protecting from deteriorating at a wide temperature range from cryogenic temperature to high temperature. At the same time, it can protect from humidity, fire and erosion. It is praised as “permanent thermal insulating material with no need of renewal”, because it is not only safe but also durable in rigor conditions of low and cryogenic temperature, underground, open air, flammability, moisture sensitivity and even chemical erosion. Consequently, it is widely applied in permanent projects as heat and cold insulating material, such as in the industries of petroleum, chemical engineering, architecture, refrigerated warehouse, underground project, shipbuilding, national defense and war industry.
