TMC for Water Purification Membranes the possibility for human contact. General Information. TMC is an important building block in the production of polymer membranes useful for fluid purification via reverse osmosis (RO) techniques. An important application for TMC in water purification membranes involves interfacial polymerization of meta-phenylene diamine (MPD) with 1,3,5-benzenetricarbonyl trichloride producing a crosslinked polyamide (US 4,277,344). More recently, TMC has been used for the synthesis of controlled porosity polyester... (read more)

Fibrous-Porous and Inert Filtration Membranes of producing membranes to meet special requirements. Zitex structures are able to handle virtually any corrosive fluid at temperatures as high as 550°F and as low as the cryogenic range of -450°F. This, of course, makes Zitex ideal for a wide variety of filtering and venting applications. Zitex is chemically inert, doesn't retain or impart odors, flavors, or contaminants and will not support growth of either bacteria or fungi. Another plus is its ability to be sterilized repeatedly with steam... (read more)Browse Filter Elements Datasheets for Saint-Gobain Plastic Films and Tapes
