polyurethane foam insulation layer

It is showed in the test result that polyurethane foam heat-insulation layer has advantages such as weight light, strength high, absorbing water rate low and high heat -insulation effect and so on.

测试结果表明，聚氨酯泡沫保温层具有重量轻、强度高、吸水率低、保温效果好、离火自熄等特点；

Besides the complex plywood to be prepared by polyurethane foam taking as the core layer, and also the test measuring analysis had done for the absorbing and sound insulation.

另外，还制备了以聚氨酯泡沫为芯层的复合板材，并对它们的吸隔声性能进行了测试分析。

Using insulation layer of ultramicropore high-density polyurethane foam, loss of cooling capacity is reduced to ensure better insulating effect and to achieve energy saving.

采用超微孔高密度聚胺酯发泡保温层，减少冷量流失，保温效果佳，实现节能降耗。
