Graded Pore Structure PP Membrane Hydrophobic Polypropylene Nominal Prefilter

Graded Pore Structure Polypropylene Nominal Prefilter For Built-In Prefiltration

Polypropylene Nominal Prefilters from XINNA are manufactured using 100% virgin polypropylene media. As a tough, durable and non-toxic filter medium with uniform strength and graded pore structure, polypropylene membranes are well suited for applications that require general clarification, prefiltration and deep filtration. Its natural hydrophobic properties, chemical stability, durability, and compatibility with acids and bases make it ideal for deep filtration applications. Our company takes pride in offering tailored solutions to cater to the specific needs of to each customer, including customizing the pore sizes, formats and further processing the PP membranes into hydrophilic type. Whether you require pre-filtration for medical or laboratory purposes, our polypropylene filter membranes could provide effective and reliable performance with minimal drawbacks.

Features of Polypropylene (PP) membrane

• High porosity
• High temperature resistance
• High retention efficiency
• High flow rate
• Excellent dirt-holding capacity
• Low extractables
• No fiber shedding
• Excellent chemical stability and compatibility with a pH tolerance range from 1 to 14

Polypropylene nominal prefilters are characterized by their properties to withstand a variety of organic solvents and maintain excellent chemical stability and compatibility. They can withstand a pH range from 1 to 14, making them highly compatible with acids and bases, they are therefore a favored choice for general clarificaton and pre-treatment of aqueous solutions and organic solvents. PP membrane filters are also commonly used for the retention of large paricles due to their low level of extractables. This property provides a perfect solution for accurate analysis in chromatographic correlation applications. Polypropylene membrane filters are extensively used in various medical and laboratory applications. For instance, they can be used as built-in prefiltration membrane in IV lines for gas venting or IV drug filtration, and they can also serve as an direct and effective pre-filter for HPLC sample preparation, solution filtration, solvent filtration, or incorporated in syringe filters for laboratory applications.
