Poly-vinyalchol Filter cloth which made of Poly-vinyalchol fiber (PVA), can be divided into PVA staple Filter cloth and PVA long thread Filter cloth. These products possess the properties of weak acid-resistance, alkali-resistance, high mightiness, specific gravity of 1014g/squ.mt, melting point of 215-250degree, and operating temperature maximum 130degree. They can also be divided into PA6 series and PA66 series, and the later performance is better than the former. They are mainly used in the chemical, coal mine, building materials, melting industrial, for the equipment in the strong alkali operating conditions, such as frame press filter, disc filter, and centrifuge filter. The filtering precision can reach less than 5 microns.
It can be divided into PA staple fiber filter cloth,
PA multifilament (long thread)filter cloth ,
PA monofilament filter cloth ,
PA multifilament/monofilament filter cloth .

?Low background, interference-free chemical determinations
?Low tare mass for accurate gravimetric results
SUITA PTFE filters are strong and completely resistant to acids, bases, and all solvents. Use PTFE filters when sampling in aggressive environments. A low chemical background makes PTFE filters ideal for sampling low concentration contaminants. Naturally hydrophobic, PTFE filters feature a low tare mass for accurate gravimetric determinations SKC PTFE filters are temperature-stable to 527 F (275 C). The maximum operating temperature for Teflon filters with PMP support ring is 464 F (240 C). PTFE filters are prone to static effects. For the most accurate sampling use a static eliminator.
Vinylon fiber chemical called polyvinyl alcohol, and its strength is lower than PET, the strength of only 5.32-5.72Cndtex, elongation 12-25%, poor flexibility, poor shape fabric, good wear resistance, durability cotton than 1-2 times, but one of the greatest advantages is that we can withstand the role of alkali and good moisture absorption, easy to combine with the rubber, rubber industry, with good use of materials, its drawback is that temperature lower temperature of 100 degrees there is contraction acid intolerance.
