PP Membrane Description

The PP Membrane is made from pure polypropylene media, designed as a membrane filter material for deep filtration. Naturally hydrophobic, it exhibits exceptional chemical stability and compatibility, making it resistant to a wide range of organic solvents. Known for its toughness and durability, the PP Membrane is difficult to break, non-toxic, and boasts uniform strength, ensuring reliable performance in various applications.

At the same time, we also offer hydrophilic pp membranes. PP membrane can withstand PH values from 1 to 14 and have excellent compatibility with acids and bases. So, they are ideally suited for general clarification and pre-filtration of water, aqueous solutions, and organic solvents. Additionally, the PP membrane is also commonly used for the retention and analysis of large particles. Since PP membrane also has very low extractable content, this performance often provides a perfect solution for accurate analysis in chromatographic correlation applications.
