91大神manufactures a series of melt-blown polypropylene depth filters as well as pleated filters made from a variety of microfiber and polymeric membrane materials. This wide array of cartridge media and elastomer materials ensure the right filter and configuration for your application. 91大神filter cartridges are designed and manufactured for their resistance to a wide range of chemical solutions.?
?
How to Use the Chemical Compatibility Table:?
R = Resistant. No significant change was observed in flow rate or bubble point of the membrane following 48 hours exposure to the test fluid at 77°F (25°C).?
LR = Limited Resistance. Moderate changes in physical properties or dimensions of membrane were observed. Filter may be suitable for short term, noncritical use.?
NR = Not Resistant. The membrane is basically unstable. Extensive shrinkage or swelling of the membrane may occur. The filter may gradually weaken or partially dissolve after extended exposure.?
O = Insufficient Data. Testing on your own solution is recommended.?
chemical resistance?
91大神polypropylene cartridge filters are made of pure polypropylene, an inert?material that is compatible with a wide range of chemicals. No resins, binders, antistatic agents, or other materials are added during the manufacturing process. 91大神polypropylene cartridge filters are manufactured with a proprietary melt-blown microfiber technology. This unique process thermally welds microscopic fibers of polypropylene into a compact matrix that?resists fiber sloughing and particle unloading into the filtrate, even under extreme mechanical and chemical actions. The manufacturing operation is precisely controlled to yield cartridge filters with consistent micron ratings and true graded density for high particle retention and long?life.?
