Description of PP Filter Membrane:
Hawach polypropylene filter membrane is a hydrophobic membrane, with good chemical stability. Ultrafine fibers are hot-melted and adhered together, so polypropylene filter membranes are a kind of membrane material for deep filtration.
Advantages of Hawach pp membrane filter:
- Disc Membrane Pore Size: 0.1, 0.22, 0.45, 0.8, 1.0, 3.0, 5.0, and 10.0μm.
Diameters: 13, 25, 47, 50, 60, 90, 100, 106, 142, 150, 200, 250, and 293mm.
Roll Membrane Pore Size: 0.1, 0.22, 0.45, 0.8, 1.0, 3.0, and 5.0μm.
Width: 270mm - The PP filter membranes are provided by the HAWACH pp membrane filter manufacturer and divided into roll membranes and sheet membranes.
- As a pp membrane filter manufacturer, HAWACH uses food-grade polypropylene as raw material, the whole production process does not contain any additives; the physical and chemical properties are stable, and it has good compatibility
- Polypropylene filter membrane has various series of pore sizes, high porosity, large dirt holding capacity, recoil, and high-temperature Disinfection; good pressure resistance.
- PP membrane filter is a hydrophobic microporous membrane with good chemical stability and good chemical compatibility in both aqueous and alcohol solutions. It is suitable for high-performance liquid chromatography, gas separation and photoresist production, and other fields.
Features of PP Filter Membrane:
- Hydrophobic membrane
- It is the second anti-corrosion membrane after the PTFE filter membrane and PVDF filter membrane.
- Good thermal stability
- Good chemical compatibility in both aqueous and alcoholic solutions
- Suitable for high-performance liquid chromatography
- Can effectively bind protein, DNA, and RNA
- The PP filter membrane is made of polymer material, is non-toxic, and can be widely used in medicine, the chemical industry, food, beverage, and other fields.
- With excellent chemical properties, it is resistant to acid, alkali, and solvent, including polar solvents (except benzene xylene, etc.).
- Temperature resistance: it can be sterilized by autoclaving at 121°C for 30 minutes, and the working temperature is below 100°C.
- Good strength, no deformation, no medium falling off, no re-pollution.
- Small resistance, fast flow rate, and high flow rate can be achieved under the condition of low-pressure difference, long service life, especially suitable for high-viscosity filtration, and the filtration of items with a lot of suspended matter, the longer the filtration time, the higher the filtration accuracy.
Applications:
- Mostly used for the filtration of organic solutions
- HPLC Sample Filtration
- Ion-Exchange Chromatography Sample Filtration
- Gas separation and filtration
- Production of photoresist materials
