Using PTFE resin as raw material, ePTFE sterilizing and efficient bubble point film is made through special processes, biaxially stretching, and utilizing the unique node fibrillary property of polytetrafluoroethylene film, with smooth surface, chemical resistance, air permeability, water impermeability, high flow rate and low pressure difference, flame retardant, high temperature resistance, strong acid and alkali resistance, and non-toxic characteristics. The product is made with high filtration accuracy and fast filtration speed; Long service life widely used in the biopharmaceutical industry and semiconductor industry for acid, alkali, organic solvents, and gas sterilization and impurity removal filtration.
