GELLEC Breathable Film

 Product Advantage 1、Can filter  virus directly, excellent protective performance. Water permeability resistance               Hydrostatic pressure resistance                  ≥Level 4 Surface resistance to water      Touch water Level                                ≥Level 4 Resistance to synthetic blood penetration        ≥Level 3 Particulate matter（0.3μm）Filtration efficiency≥99.9%, can filter virus directly. 2、Breathable, low weight, high comfort. Moisture transmission  3500g/g㎡*d, meet long wear requirements. Breathable   GURLEY values in 20～100s/100ml Low weight     4～15g/㎡can meet the protection requirements. 3、Tear resistance and wear resistance High breaking strength, the transverse breaking strength is more than 4 times that of conventional breathable film. Excellent puncture resistance，φ1mm acupuncture intensity is higher than that of conventional permeable membrane 2N   Product Features 1、Mean aperture small（40-60nm）, Lower than the diameter of most known bacteria and viruses，effective physical barrier, antivirus. 2、Extraction into a hole，uniform aperture，high sinuosity，barrier path length，excellent filtration efficiency. 3、The wet process is used for bidirectional high - fold drawing，pore forming uniform，the bidirectional intermolecular forces are uniform，the transverse strength is significantly better than that of conventional breathable film. 4、No or little inorganic fillers, puncture and tear resistance. 5、UHMWPE raw material, wear resistance.
