PES pleated filter cartridge

PES pleated filter cartridge, its filter media is the advanced polyethersulfone microfiltration membrane in the world. The Polyether sulfone membrane holes account for more than 80% of the pore volume, and has a unique micropore geometry, which improves the filtration efficiency and circulation of the difficult filtration solution. Using hot welding method to weld two materials of polyethersulfone and polypropylene support together, there are no cohesive substances. They are suitable for chemical and pharmaceutical industries which require more stringent requirements. The main characteristics: unique hydrophilic properties, without surface active agent and surface lubricant, provide high level filtration precision and circulation for the filtration solution; the applicable PH range is wide, the adsorption of protein and precious biological agents is low, the interception rate is high, the chemical tolerance and thermal stability are excellent, and the strength is good, resistance to positive and reverse pressure shocks.
