HanPES PS-grade Asymmetric Polyethersulfone Membrane
HanPES PS-grade membrane features an asymmetric structure: the larger pores at the inlet side capture bigger particles, while the smaller pore dense layer near the outlet side retains fine particles. The outlet surface layer protects the innermost dense layer, preventing scratches or damage.
The specially designed thickened dense layer structure provides high particle retention reliability and low permeability, making it suitable for filtration processes requiring high reliability or low particle load, such as in the biopharmaceutical and food industries.
