1> widely used in wall insulation, flat concrete roof and steel roof insulation; 2> moisture-proof insulation for low temperature storage of the ground areas, parking platforms, airport runways, highways and the like. Extruded polystyrene board is heated polymer resin combined while mixing, into the catalyst, then press out the continuity of closed-cell foam extruded rigid foam board, which is independent of the internal bubble-enclosed structure, It is a high compressive strength, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, super anti-aging (long-term use almost no aging), low thermal conductivity, excellent performance of environmentally friendly insulation material. Expanded polystyrene board (eps board) water absorption and its extruded polystyrene board (XPS board) is relatively high, easy absorption, xps extrusion board, which is a drawback of the material. Its insulation board absorption thermal conductivity effect on it is clear that with the increasing amount of water absorption, HSBC Taiwan xps extrusion board, its thermal conductivity is increased, the insulation effect also will be worse, so this special Note. EPS and XPS insulation performance of the same thickness is gradually increased. EPS 0.041, Baoding xps extrusion board, XPS 0.030. Therefore, to achieve the same insulating effect under the circumstances, XPS plate thinner than the thickness of EPS board, but the pure plate prices in EPS boards XPS plate expensive. If the full account of technology and building height, price per square meter instead XPS expensive than EPS. 1) polymer mortar configuration with special binder. 2) configured polymer mortar spread evenly on the plate thickness of 2 mm.
