ASTM C552 foam glass block cellular glass insulation

Descripción del producto

Cellular glass is a new inorganic thermal insulating material with a structure of separate closed cells.The composition is
glass,added with foaming agent.It's foamed by high temperature in foaming furnace,and then cooled down in cooling oven.
It well reserves the chemical stability of inorganic glass.As a result,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 process and able to bear all kinds of chemical erosions except the hydrofluoric acid.

Cellular glass,nontoxic in itself,has stable chemical properties and good thermal insulating performance protecting
from deteriorating at a wide temperature range from cryogenic temperature to high temperature.At the same time,it can
protect from humidity,fire and erosion.It is praised as "permanent thermal insulating material with no need of renewal",
because it is not only safe but also durable in rigor conditions of low and cryogenic temperature,underground,open air,
flammability,moisture sensitivity and even chemical erosion.Consequently,it is widely applied in permanent projects as
heat and cold insulating material,such as in the industries of petroleum, chemical engineering, refrigerated warehouse,
underground project,shipbuilding,national defense and war industry and building insulation.
