PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. Difference from glass fiber membrane, PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene.
determination of heavy metals in plastic materials. The precipitate, if formed, was filtered off by a membrane filter. The metals were determined by ICP-AES. The sample digestion required 5 min (for 20-mg sample) to 25 min (for ... 25-ml PTFE vessel, and 1.5 ml of nitric acid and 0.5 ml of

Our unsupported, hydrophobic, PTFE membrane filters are ideal for sterilization and venting applications involving air, gasses, and solvents/acids incompatible with most other filters. Read More These PTFE filters are chemically and biologically inert, stable up to 260°C, and will withstand the majority of concentrated acids and bases and are
Disclosed is a porous membrane comprising a porous polytetrafluoroethylene (PTFE) substrate and a coating comprising a copolymer of formula (I): H—[—O—CH(Rf)—CH 2 —] m —[—O—CHM-CH 2 —] n —[—O—CHL-CH 2 —] s —OH (I), wherein Rf is perfluoro-substituted alkyl or perfluoro-substituted alkyloxy alkyl; M is —CH 2 —O—(CH 2 ) 3 —S—(CHZ) t —Y, wherein Z is
PTFE membrane is a layer of PTFE material that removes particles of a certain size and shape, while allowing others to pass through. When applied to a substrate (such as fiberglass, P90, etc.) it removes particles much like dustcake normally would on a Baghouse filter. * See section "The Benefits of Surface Filtration"
The 32235 has a 12 mm sensor filter. It is metal-coated PPS plastic with a PTFE membrane. The pore size is 0.2 µm. The 32235 may be ordered to replace a lost or damaged filter and cap.

In 2004, Feng et al. [ 11] adopted spray deposition method to deposit a PTFE coating on the surface of a stainless steel mesh to prepare an oil-water separation filter membrane with superhydrophobic and superoleophilic properties, as shown in Fig. 2, and applied this special wetting filter membrane to oil-water separation.
