2021年9月30日 · For filter makers, our best-in-class membranes provide many benefits that ensure their reliability in semiconductor and microelectronics processing, like: proven higher liquid flow rate at a given retention level. consistent high quality and repeatable high performance. reliably filters nanometer-level particles and harmful contaminants.
Filter Membranes. Produced by the precipitation or stretching of polymeric materials, membrane filters are commonly used in both industry and research. Properties of membrane filters vary widely with differences in composition, surface treatments, and pore size. Selecting the ideal filter requires an understanding of basic characteristics.

GVS Laminated PTFE filters are made of a polytetrafluoroethylene polymer (PTFE) laminated to a polypropylene support for improved durability and easy handling. These filters are chemically compatible with strong acids and most aggressive solvents such as alcohols. PTFE (fine powder resin) is expanded into a 3-dimensional web-like structure
