XPS foam insulation board has more advantages than traditional insulation material with its perfect honeycomb structure. Its excellent thermal insulation, compressive strength, noise, moisture, corrosion-resistant performance, light weight, easy to cut, getting widely use in construction, road construction, refrigeration engineering and other fields. Our company independently developed the CO2 combination of foaming agents instead of the Freon foaming agents; greatly re- ducing the XPS board production costs and increase market competitiveness. Secondly, the CO2 as foaming agent is harmfulness to environment, it will annually reduce 250 tons consumption of Freon brings great social environment benefits. Therefore full compliance with the proposed global building a low carbon emissions of the industrial system and consumption patterns of development policies,, promote the global response of climate change has made new progress to make contributions.
