strength.
2. No water absorption, no permeability.
3. Low thermal expansion coefficient, no deformation, no crack.
4. Incombustible and corrosion resistance.
5. No mildew, no rat biting, no aging and no deterioration.
6. Having the same duration with buildings.
7. Environmental friendly and recyclable.
Cellular glass is a kind of inorganic rigid insulation materials,
which is non-toxic, harmless, environmentally and friendly. It can
be applied to cryogenic and high-temperature environment, and it is
the best comprehensive low-temperature thermal insulation material.
Cellular glass is not only a cold insulation but also a thermal
insulation material, which can be used from deep cold area to
thermal state. At the same time, after long-term use it will not be
deteriorated and and it plays an important role in fire prevention
and earthquake prevention. It is not only safe and reliable, but
also durable when it is used in the harsh environment of low
temperature, deep cold, underground engineering, inflammable,
explosive, humid and chemical erosion. It is known as "permanent
thermal insulation material that does not need to be replaced".

Application
As an advanced thermal insulation material, cellular glass is
widely used in petroleum industry, chemical industry, underground
engineering, shipbuilding and defense works. It can be used in the
cryogenic insulation system in pharmacy, the cryogenic system in
hydrocarbon processing, the low temperature piping, equipment and
storage tank, the cold storage and cold storage building, the steel
liquid oxygen, liquid nitrogen storage tank and pipeline, and
rxterior wall insulation, exterior insulation, roofing, basement.
