Xps Extrusion line is used to produce one kind of excellent adiabator that we call Xps Foam Board . This board is superior to traditional heat resistant material, because of its honeycomb structure.It has excellent heat-sound insulation performance, high impact resistant, anti-corrosion property low density and easy cutting that make it very popular in building, road construction and refrigeration project and so on. Advantage of our productionThe aerating agent is the key part of the machine. Usual aerating agent is Freon Butane and carbon dioxide. Through our many years testing, we have developed a set Xps Extrusion line that carbon dioxide foam technology is used. Carbon dioxide foam technology has advantage of environment friendly and low cost than other aerating agents.
