1.
ePTFE porous membrance for air filter. Space rate is about 82%, average hole diameter is about 0.3um,The membrance has special functions of high Breathability excellent chemistry stability, small friction quotiety high temperature resistness etc. After laminated with the 99.99%. It's the best choice for any kind of High Effciency Particulate Air Filter.
2.
Because the PTFE membrance has a structure of multi-holes,and the diameter of the hole is much bigger than water vapor and much smaller than a water drop. The PTFE membrance has a character of extremely breathable, durably waterproof and windproof. It is the optimum solution for who need to face extreme weather and tough counditions after be laminated with special fabrics. Such as firefighter, enthusiasts.etc.
