Description
These filters are made from polypropylene ultrafine fibers via hot melt bonding, providing excellent deep filtration capabilities. Manufactured from food-grade isotactic polypropylene without additives, they are known for their superior chemical resistance and mechanical strength, making them ideal for various industrial and laboratory applications.
Distinctive Features:
- Hydrophobic polypropylene membrane offering excellent chemical resistance to acids, alkalis, solvents, and polar solvents.
- High porosity and uniform pore structure for efficient filtration.
- Excellent pressure resistance and high-temperature sterilization capability.
- High dirt-holding capacity, suitable for large-scale filtration processes.
- Good compatibility with aqueous and alcoholic solutions.
- Stable physical and chemical properties, ensuring reliability and consistency.
- Economical membrane filter option with various pore sizes and customizable options.
Recommended Uses:
- Filtration of organic solvents, acidic and alkaline solutions (excluding hydrofluoric acid).
- Liquid and gas filtration, particularly in harsh chemical environments.
- High-temperature applications where sterilization via pressure steam is required.
- Membrane degassing, membrane distillation, and membrane pervaporation.
- Pre-filtration of samples with high filtration speed using 0.45 µm membrane filters.
- Industrial and laboratory filtration applications requiring robust chemical compatibility.
