Foam glass (cellular glass) is a new kind of inorganic heat
insulating material with a structure of equallyclosed cells. It is
mainly made of glass added with adequate foaming agents after
heating and baking in high-temperature tunnel furnace, then
annealing and cooling. Because it well reserves the chemical
stability of inorganic glass, it has the following features: low
density, low thermal conductivity, vapor impermeability, no water
absorption, incombustibility, protection from mould and rat eating,
high mechanical strength but easy to cut and able to bear all kinds
of chemical erosions except the hydrofluoric acid.
Foam glass (cellular glass), nontoxic in itself, has stable
chemical properties and good heat insulating performance protecting
from deteriorating at a wide temperature range from ultra-low
temperature to high temperature. At the same time, it can protect
from humidity, fire and erosion. It is praised as permanent heat
insulating material with no need of renewal” because it is not only
safe but also durable in rigor condition of low and cryogenic
temperature, underground, open air, flammability, moisture
sensitivity and even chemical erosion. Consequently.
Foam glass (cellular glass) is applied widely as follows:
1.Chemical Industry： Reaction equipment, chemical pipes, oil pipes,
LNG pipes, LPG pipes, tank bottoms and insulation projects,
etc.2.Architecture: refrigeratory, ship-building industry, roof
heat-preservation, inside and outside wall heat-preservation,
parking lot and insulation of inner layer of chimney,
etc.3.Underground Projects: subways, underground storerooms and
tunnels, etc.4.Others: Military industries, pumice, air-separator
pipes, cold liquid tank bottom insulation, etc.Characteristics of
high Performance foam glass (cellular glass):
1. Applicable for both cryogenic and high temperature.
2. Low thermal conductivity but high compressive strength
3. No water absorption, no permeability, excellent airtight
4. Low thermal expansion coefficient and good dimensional
5. Totally not combustible, fireproof, and corrosion resistant.
6. Nontoxic, harmless, and environmental friendly.
