PP sintered filter cartridge is made from polypropylene powder and is known for its excellent chemical resistance, thermal resistance, and mechanical strength. It is a cost-effective option that can be used for the filtration of a wide range of liquids, including acids, alkalis, and organic solvents. The pore size of PP sintered filter cartridge typically ranges from 0.2 to 100 microns, making it suitable for both coarse and fine filtration applications. Additionally, it has a high surface area and porosity, which enables it to retain large amounts of particles.

PE sintered filter cartridge, on the other hand, is made from polyethylene powder and has a lower chemical and thermal resistance than PP sintered filter cartridge. However, it has a higher porosity, which makes it an excellent choice for filtration applications that require high flow rates and low pressure drops. Its pore size typically ranges from 0.1 to 70 microns, which is suitable for fine filtration applications.

In summary, PP sintered filter cartridge and PE sintered filter cartridge are two types of filter cartridges that are suitable for different types of filtration applications. PP sintered filter cartridge is cost-effective, chemically and thermally resistant, and suitable for both coarse and fine filtration applications, whereas PE sintered filter cartridge has a higher porosity, and is suitable for filtration applications that require high flow rates and low pressure drops.
