The pore size of the ptfe waterproof breathable membrane is small and uniform, the micropore structure is stable, the porosity can reach 80%~90%, and the filtration accuracy can reach above U15 level, or even reach U17 level.
The surface filtration efficiency reaches 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
