The new microfiber is a completion of Advansa's product portfolio in the direction of finer fiber. Further microfiber at 0.3 and 0.5 dtex, as well as regular fiber with 1.7, 3.3, 6.7 and 17.0 dtex, are available and well established options for filtration media developers to control filter key parameters like efficiency, pressure drop, mechanical strength, thermal stability and many others. Most of those fibers meet the requirements for food contact applications according to EU, BfR and FDA regulations. The options are completed by various core-sheath-binder fibers with polyester core and co-polyester or polyolefine sheath with melting ranges around 110, 130, 160 and 180°C. Thus, a wide range of high quality wetlaid filtration media for many purposes and process routes can be engineered using ADVA shortcut as base material.
