2021年12月27日 · SSI Aeration, Inc. creates multi-layer PTFE membranes that reduce scaling, fouling and cleaning frequency. As the worldwide choice of PTFE membrane
Hydrophilic PTFE Membrane Cobetter hydrophilic PTFE membrane is made of pure PTFE membrane bonded to a polypropylene non-woven support. The extreme chemical compatibility (pH 1-14) makes it an ideal material for filtration of almost all solvent, acids and alkaline solutions, and organic-based aqueous samples, and is commonly used for HPLC

The most common membrane materials we offer are PES (polyether sulfone) and PTFE membranes. PTFE membranes are most often specified for water filtration applications like bottle filling, produce wash down, or other food industry processes. Polysulfone allows easy manufacturing of membranes, with reproducible properties and controllable size of
Expanded polytetrafluoroethylene (PTFE) is an exemplary biomaterial. In addition to possessing the basic properties of PTFE, ePTFE products offer a number of beneficial properties. The combination of these two sets of properties makes possible a vast number of applications for medical devices containing ePTFE.
2022年5月1日 · The absorbance results of human foreskin fibroblasts (HFFs) after 1 and 3 d of culturing on PTFE-SO100, PTFE-SO350, PTFE-SO1000, and ES-PTFE surfaces are shown in Fig. 6(b). On day 1 of incubation, the number of living cells for the PTFE-SO100 and PTFE-SO350 groups differed significantly from that for PTFE ( p < 0.001).
2022年8月5日 · The superior stability of PTFE membrane can be explained by the ultrathin membrane thickness and the hydrophobicity, which are good for clearly washing. Fig. 6 shows the variation of filtration resistance of Cambridge filter and PTFE-5 membrane at different smoke flow rates.
Since 1958, Gore has developed products that improve lives. At the center of these solutions is polytetrafluoroethylene (PTFE), a polymer with exceptional properties like high tensile strength, a low dielectric constant, UV resistance and many more. In 1969, the possibilities for PTFE expanded with Bob Gore’s discovery of expanded PTFE, or ePTFE.
PTFE, or polytetrafluoroethylene, is a PTFE-coated woven fiberglass membrane. that is extremely durable and weather resistant. PTFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with an expected project life exceeding 30 years. PTFE fiberglass coating is chemically inert, capable
2006年1月1日 · Thus, a 0.2-µm liquid-rated membrane will perform in air at the rate of a membrane that would be rated at 0.02 µm if it were rated in air. 1 Although it is well known that IV filters incorporate 0.02–0.03-µm PTFE membrane as vents, the filter characteristics should not be considered part of the bacterial or viral retention characteristics for all
2023年1月28日 · N95 masks have a filtration efficiency of at least 95% for NaCl particles 100–300 nm in size. When the certified flow rate is 85 L/min, the filtration efficiency reaches 99.5% or higher at about 750 nm. The removal rate for environmental particles with submicron particles smaller than 750 nm can be up to 100%.
