For the polycarbonate track-etch (PCTE) and polyester track-etch (PETE) membrane filters, porosity is the percent of the total surface area occupied by the pores; it typically ranges from <1% to 16%. For the other membrane filters, porosity is the percent of the
Membrane Material: Polytetrafluoroethylene (ePTFE) Support Material: Polypropylene (PP) Sealing： PTFE membrane can be laminated to various support materials by heating，and no adhesive, surface active agent are used during the production of membrane. Environment: produced and tested in clean room of10,000 class and all relevant staff must wear clean

late 1960s, 0.45 m-rated membranes were considered "sterilizing grade" filters, and were used successfully in the sterilizing filtration of parenterals. Such filters were qualified using 0.6x1 µm Serratia marcescens , a standard
Professional Plastics offers a wide variety of medical grade plastic materials that meet FDA and USP Class VI requirements. Our high-purity materials have been used in applications from Medical Wands to Sterilization Trays and Endoscopic Probes & Devices
Increased porosity of e-PTFE membranes causes an increase in bacteria migration and tissue ingrowth within the porous membrane. Another PTFE membrane known as non-expanded and dense/non-porous PTFE (n-PTFE) can be used; n-PTFE has a smooth outward face which can prevent tissue ingrowth, but this can ultimately lead to poor socket flap adhesion and increases the possibility of tissue dehiscence
2018/6/15 · This study aimed to compare standard hydrophobic PTFE membranes used for MD with a novel hydrophilic-coated PTFE membrane material for the treatment of textile industry wastewater. Uniquely in this work, the approach of the trial was the treatment of effluent directly from the plant, for a future vision of intensified membrane processing of wastewater when compared with the current use
Standard Specification for Polytetrafluoroethylene (PTFE) Granular Molding and Ram Extrusion Materials 1 This standard is issued under the fixed designation D 4894; the number immediately following the designation indicates the year of original adoption or, in
Our LifeASSURE PFS series PTFE Filter Cartridges use a hydrophobic polytetrafluoroethylene (PTFE) membrane, which helps minimize pore blockage from moisture in vent applications. Our filters are validated by a liquid bacterial challenge for complete retention based on the ASTM standard, which provides a high level of reliable sterilizing performance.
