采用压缩模塑法制备了聚乙烯远红外窗口，对红外窗口材料的成型条件和性能进行了测试分析。结果表明，成型温度为150℃，样品的成型压力对红外透过率没有影响，窗口材料的红外透过率随厚度的增加而减小，最后选定样品厚度为2mm，在15μm以后具有较好的透过率。抗腐蚀性能测试结果表明，材料耐强酸、强碱及部分有机溶剂。

The polythene infrared window is obtained by compress mould method. The molding conditions and performance of the infrared window are analyzed. The results show that molding temperature is 150℃. The infrared transmittance is not affected by molding pressure. The transmittance of infrared window materials is decreased with the increasing of the thickness. At last the thickness of the sample is selected as 2 mm, and the transmittance of sample of 2 mm thickness is good at 15 microns wave band. Anti-corrosion test results prove that the material is able to bear strong acid, strong base and part organic solvent.
