Foam glass is a new inorganic thermal insulation material.Mainly made from glass powder and well reserves the chemical stability of inorganic glass, foam glass thereby possess the following features of low density, low thermal conductivity, non- aging, high durability. After finely pulverized and uniformly mixed, it is melted, foamed and annealed at high temperature Into inorganic non-metallic glass materials. It is composed of a large number of uniform bubble structure with a diameter of 1 ~ 2 mm.

1, itself non-toxic, non-radioactive, will not release harmful substances, will not pollute the foundation and groundwater, environmentally friendly materials; 2,non-burning, moisture absorption and low water absorption, the use of temperature range, the actual use of ordinary foam glass temperature is 240 ~ 280 ℃;
3, not easy to weathering, aging, free from rat bites and microbial corrosion; 4, by changing the formula and foaming process, adjust the bulk density, open porosity and closed porosity and other properties.

1, foam glass substrate is glass, it is not absorbent. The internal bubbles are also closed, so there is no capillary phenomenon, it will not penetrate, so foam glass is currently the best insulation materials.
2,high mechanical strength, strength changes and apparent density is proportional to. Has excellent compressive properties, more than other materials withstand the erosion of the external environment and load. Excellent compressive strength and moisture resistance combine to make foam glass underground pipe and tank foundation ideal insulation material.
3, foam glass has a good adiabatic moisture permeability, thermal conductivity and long-term stability, not due to changes in environmental impact, good thermal insulation properties.
4, foam glass substrate wet glass, it will not spontaneous combustion will not be burned, is an excellent fire-resistant materials. Foam glass working temperature range of -200 ~ 430 ℃, the expansion coefficient is small (8 × 10 ℃) and reversible, so the material properties of long-term stability, not brittle, good stability.
5, foam glass sound insulation performance, a strong absorption of sound waves, the average penetration loss in the 60 ~ 400Hz 28.3dB.
6, foam glass dyeing performance, can be used as insulation decorative materials.
