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
