Cold Insulation Material

Foam Glass ASTM Standard Description 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. As a result, it has the following features: low density, low thermal conductivity, vapor impermeability, no water absorption, non-combustibi
