FilmTec™ reverse osmosis membrane elements are very effective at industrial process water treatment. In many industrial systems, RO elements also serve as pretreatment for ion exchange (IX) resin beds. Because of its exceptional properties, FilmTec™ technology can help lower capital investment, reduce operating costs, and allow for greater
2020年4月27日 · Commercially available nonresorbable membranes are Gor-tex (e-PTFE), Cytoplast (d-PTFE), and titanium mesh. Resorbable membranes are available as natural and synthetic. Clinical trials, a systematic review and meta-analysis have shown no statistically significant difference in most clinical indications between both types of
Polytetrafluoroethylene membrane (PTFE membrane) is a synthetic material that expands to form a microporous film (also called Teflon film/membrane) and can be laminated to functional fabrics. The microporous PTFE has waterproof, windproof, and heat-resistant properties which are used to produce waterproof breather membrane, and is ideal for
The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity. The store will not work correctly in
2022年11月1日 · Advantages of Porex Virtek® PTFE Membranes. Robust and durable sintered PTFE due to 3D matrix construction. Naturally hydrophobic for waterproof venting. Self-supporting membrane that is easy to handle and omni-directional. UL-94 flammability and UL-746C weatherability listings. Reflecting property to diffuse light or radiation.
2017年5月1日 · 1 Introduction. As is known to all, polytetrafluoroethylene (PTFE) as engineer materials has excellent physical and chemical properties, such as outstanding thermal stability ( 1) and toughness at low temperature ( 2 ), low thermal conductivity, perfect insulating and dielectric properties ( 3 ), extremely low coefficient of friction ( 4) and
