Folding membrane filter element
Material Introduction:
1. Polypropylene composite filter (POLYPROPYLENE): the main filter material, this filter element is an advanced fixed deep filter element, the nominal filtration accuracy range from 0.1μm to 60μm. The filtration accuracy is not affected by the fluctuation of feed pressure. Its unique low pressure difference, high flux, good filtration accuracy and low economic costs and other advantages, favored by the majority of users
2. Polypropylene microporous membrane filter core polypropylene filter core: it is a kind of ultra-fine polypropylene fiber filter material as the filter medium with fixed aperture deep filter core, the filter material meets the relevant requirements of FDA. Filter accuracy range from 0.1um to 60um, its unique low pressure difference, high throughput, long service life characteristics, is the preferred pre-filtration products. All polypropylene structure has stable properties and wide chemical compatibility.
3. Hydrophobic POLYtetrafluoroethylene filter core: its filter medium is hydrophobic polytetrafluoroethylene microporous filter membrane: strong hydrophobicity, high rejection rate, good chemical tolerance and thermal stability, good strength, resistance to positive and reverse pressure impact.
4. Hydrophilic POLYtetrafluoroethylene filter core: its filter medium is hydrophilic polytetrafluoroethylene microporous filter membrane: hydrophilic stability, high retention rate, good chemical tolerance and thermal stability, good strength, resistance to positive and reverse pressure impact.
5. Polyethersulfone filter core: its filter medium is the world's advanced polyethersulfone microporous filter membrane. The pore of polyethersulfone membrane occupies more than 80% of the volume of the filter membrane, and has a unique microporous geometry, which improves the filtration efficiency and flux of the difficult solution. It is composed of polyethersulfone and polypropylene supported by two kinds of materials, and has no adhesive. It is suitable for chemical industry and pharmaceutical industry with strict requirements. Main features: unique hydrophilicity
