HUZHOU SENNUO FLUORINE MATERIAL TECHNOLOGY CO., LTD.

EPTFE waterproof and breathable membrane is made of PTFE resin as raw materials, through special process, like two-way stretch, using unique technology for forming between 100-500nm in diameter of microporous membrane, and per square centimetre has more than 10 microporous, which is 700 times larger than the water vapor molecules, 10000 times smaller than water molecules. It makes the membrane allows both air and water vapour freely through the membrane,also can keep the water out of at the same time. So it can protect the service life of electronic components.
