I. Introduction
Foam glass is a new type of inorganic cold insulation material made
primarily from glass, mixed with appropriate foaming agents, and
produced through high-temperature foaming in a kiln followed by
annealing and cooling. It features a uniform structure of
independent closed cells.
II. Scope of Application
Foamglass Insulation Systems Provide Solutions For A Wide Range Of
Piping And Equipment Applications At Operating Temperatures From
-268 To 482 C (-450 To 900 F)

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".
