孔板波纹填料是在金属薄板表面冲孔、轧制密纹，冲波纹最后组装而成的规整填料，具有阻力小、气液分布均匀、效率高、通量大、放大效应不明显等特点，应用于负压、常压和加压操作。
NC-MMP直接替代广泛使用的Sulzer Mellapak
NC Metal MELLAPAK PACKING (NC-MMP)
MMP is clear and neat filling assembled and small and large corrugation rolled on basis of thin board surficial holes．It has characteristics such as small resistance，even gas and liquid distribution，high efficiency，largeflow rate and unremarkable magnifying effects etc．It's applied to negative pressure，normal pressure and pressurization operation．
Size(X,Y):SM-125 ,SM-250,SM-350,SM-450
