Description of Polypropylene Membrane Filter
PP membrane filters (Polypropylene) are hydrophobic membranes, which are resistant to a wide range of organic solvents with excellent chemical stability and compatibility (apart from hydrofluoric acid and bases). Polypropylene membrane filter is widely used as the most economical membrane filter. 0.45 membrane filter can also be used for pre-filter for samples with a high filtration speed. Although hydrophobic, polypropylene membrane can still be used with water and aqueous solutions after wetted with alcohol (or similar water-miscible low surface tension fluid).
Microporous membrane filter 0.45 μm is made of polypropylene ultrafine fibers by hot melt bonding, which is a kind of membrane material for deep filtration. As a polypropylene membrane filter suppliers, the pp membrane is made of food-grade isotactic polypropylene, without any additives in the whole production process.
PP membrane has stable physical and chemical properties and good compatibility; polypropylene membrane filter has a series of pore sizes, high porosity, large dirt holding capacity, recoil and high temperature disinfection; good pressure resistance.
