---4M-ePTFE
4M-ePTFE membrane takes polytetrafluoro ethylene (PTFE) as raw material, which is made of special process. The surface of membrane is covered with fibrous micropores, which have up to 90 billion micropores per square inch, with excellent waterproof, breathable, water vapor permeability, keeping warm effect.
The hydrostatic pressure for 4M-ePTFE membrane could reach up to about 18000mm of the water column, which can withstand heavy rain. The U.S. military standards are only 7000mm water column.
The micropore diameter of the 4M-ePTFE membrane is about 0.2μm, the diameter of light rain is 400μm, the diameter of heavy rain is 3000μm, the diameter of rainstorm is 6000 μm above. So whether the rain is light or heavy, 4M-ePTFE membrane can effectively block them.
The water vapor permeability for 4M-ePTFE membrane could reach 32603g/m2.24hr, and the general waterproof breathable fabric is only 2000-3000g/m2.24hr.
Due to the diameter of water vapor molecule is 0.0004μm, and the micropore diameter of 4M-ePTFE membrane are a few hundred times greater than water vapor molecules, and at the same time with the drive of temperature difference and the vapor concentration difference inside and outside the membrane, so sweat vapor easily excreted through the micropores, and will not accumulate and condensate between skin and fabric, and make human body to keep dry and comfortable.
The index which mostly reflect the fabric water vapor permeability performance is water vapor resistance. The 4M-ePTFE membrane of the water vapor diffusion resistance is less than 4, and its performance is much better than domestic and international similar products.

Product Application---Military products
Due to 4M-ePTFE membrane with a high chemical stability, waterproof, water vapor permeability, windproof, breathable, acid and alkali resistant, anti corrosion and anti bacteria functions etc., the composite fabric based on 4M-ePTFE membrane has a wide application prospect in the army: such as military field clothing (especially waterproof breathable land and naval combat clothing and training clothing, which is necessary choice for army and navy in the training and combat) and military outdoor products, medical protective clothing and chemical protective clothing, firefighters clothing and other field work occupation clothing;
The test index comparison between the composite fabric of 4M-ePTFE membrane and the international general military uniform are as follows:

Product Application---Outdoor clothing
At present, the competition of outdoor clothing market is very fierce, with so many product variety, quicker replacement speed. The people who can better grasp the product launch time can lead the stage market trends, which has become an essential weapon for outdoor sports brand enterprises to participate in market competition.
Compared with the United States 's top brands such as Gore and other competitors, 4M-ePTFE membrane owns the same level in the quality and technical indexes with similar products, and even individual index has surpassed the opponent. Moreover, outdoor sports apparel competition is becoming increasingly fierce, the use of Gore-tex, eVent and other apparel fabrics will make enterprise bear tremendous pressure in the production costs, and there are many companies who exit from Gore-tex ecosystem, therefore in the domestic outdoor sports apparel market, we are fully capable of competing with big companies.
