Differences between EPS sandwich panel and Rock wool sandwich
EPS (Expanded Polystyrene) is a polymer containing molecules composed of carbon and hydrogen atoms, typically eight of each. The molecular formula of polyurethane, on the other hand, describes a much more complex polymer made from molecules composed of nitrogen and oxygen as well as carbon and hydrogen.
Rockwool sandwich panel and its manufacturing process is one the most advanced inventions, which in the factory automation equipment, rock wool and steel into a whole, thus changing the way of the rock wool plate before the compound required site , under the premise that meet the requirements of the building thermal insulation, sound insulation, fire protection, to achieve a high quality, efficient, reliable, safe target.
