CN

  Polyacrylonitrile (PAN) is a kind of ideal ultrafiltration membrane material. PAN Polymer contains C-N group, with certain antibacterial such as resistant to microorganism’s erode activity. It has good chemical stability and hydrophilic. PAN hollow fiber ultrafiltration membrane is widely used in municipal water purification, household water purification, reverse osmosis pretreatment, special separation and other areas.
