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
Load-bearing cold insulation for large storage tank bottoms
Low-temperature frozen pipes and container tanks
Offshore oil platforms
Heating pipes and equipment
Building insulation and energy conservation
III. Product Characteristics
Rigid polyurethane has advantages such as low thermal conductivity, high strength, light weight, sound insulation, shock resistance, insulation, high buoyancy, stable chemical properties, and convenient construction. Meanwhile, it exhibits excellent processing performance and can be prefabricated or processed into flat panels or pipe shell shapes.
Foam glass is a new type of inorganic cold insulation material, mainly made from glass as the primary raw material, mixed with appropriate foaming agents, and produced through high-temperature foaming in a kiln and subsequent annealing cooling process, resulting in a uniform structure of independent closed cells.

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".
