Dimensions of PP Melt Blown Filter Cartridge

January 18,2022

PP melt blown filter cartridge is a tubular filter cartridge made of non-toxic and tasteless polypropylene particles through heating, melting, wire spraying, traction and acceptance forming. If the raw material is mainly polypropylene, it can be called PP melt blown filter cartridge. It is not only used in large quantities in water purification. It also has excellent chemical compatibility and is suitable for the filtration of strong acids, bases and organic solvents. It has strong pollution holding capacity, long service life and low cost. Because the melt blown filter cartridge is generally used in the field of liquid filtration, various factors should be comprehensively considered when selecting the material of the melt blown filter cartridge.


PP melt blown filter cartridge is made of polypropylene as raw material. After heating melt blown wire, it forms a deep filter cartridge with a certain aperture gradient, which is produced at one time. The outer sparse and inner dense structure can evenly intercept pollutants of different sizes in the inner and outer layers of the filter cartridge. It is often used for liquid pre filtration.


Features: strong acid and alkali resistance, high flux, chemical compatibility, multi-layer filtration without any adhesive.
