Huzhou Sennuo Fluorine Material Technology Co., Ltd ePTFE waterproof and moisture permeable membrane ePTFE waterproof and moisture permeable membrane is made of PTFE resin. It is specially processed, biaxially stretched, and uses unique technology to form ePTFE into a microporous film with a diameter of 100-500nm.It has more than 1 billion holes per square centimeter. The pores are 700 times larger than the water vapor molecules and 10,000 times smaller than the water molecules, allowing the membrane to allow both air and water vapor to pass through the membrane freely while rejecting the water. After many years of exploration and continuous improvement, special treatment on the membrane can improve the service life and wear resistance of the membrane. It Can be combined with any fabric. Clothing can add various functions to make the human body more comfortable, and is known as "breathable fabric". Testing standard: *:Water Vapor Permeability: JIS L 1099A1 *: Water Vapor Resistance: ISO11092 *: Water pressure resistance: ISO811 *: Air Permeability: ASTM D737-1996 ePTFE sterilization high-efficiency bubble point membrane ePTFE sterilization high-efficiency bubble point membrane is made of PTFE resin. It is specially processed, biaxially stretched, and has a unique node fibrility, smooth surface, chemical resistance, gas permeable, high flow rate and low pressure difference,flame retardant, high temperature resistant, strong acid and alkali resistant, non-toxic and other characteristics.The products are made with high filtration precision, fast filtration speed and long service life. They are widely used in biopharmaceutical industry and semiconductor industry, acid, alkali, organic solvent and Gas sterilization and impurity removal filtration. Test standard: * : liquid flux test pressure difference 0.02mpa temperature 25℃ pure water * : the above bubble point value is the first bubble point * : test solvent: anhydrous ethanol ePTFE air dust-removing composite material ePTFE air dust-removing composite material uses acupuncture, spunlace felt and woven fabric produced by well-known brands at home and abroad as carriers. And use the international leading composite technology: high temperature heat sealing, low temperature heat sealing, spray compounding, etc. to make the membrane and substrate perfectly combined, and concentrate on the dust precision filtration. Test standards: * Air permeability (ASTM D737 test differential pressure: 125PA) * Resistance (EN1822-3:1998) Test conditions: air flow 32L/Min filtered wind speed 5.33cm/s) * Efficiency (GB19083 EN134) test particle size (DOP): 0.1-0.3um
