Sunshine Brand insulation foam glass
?
?
SPECIFICATION
?
Foam glass is new inorganic thermal insulating material with a structure of equally close cells. The composition is glass added with foaming agent. It is foamed by high temperature in foaming oven and then cooled down in cooling?oven.
As a result it has following characteristics: low density, low thermal conductivity, vapor impermeability, high mechanical strength but can easy to cut and also able to bear all kinds o chemical erosious except the hydrofloric acid.
