Meltblown Non-Woven Fabrics for Face Masks

In addition to respirator masks, other non-woven, medical protective clothing is manufactured as well. So-called melltblown polypropylene (PP), which functions as a filter, provides the products high filtration efficiency against the smallest particles. Meltblown PP is a non-woven fabric made of extremely fine, melt-spun microfibers.

For quality assurance of the raw material, for example of polypropylene, an extrusion test is performed. The volume flow index (MVR) of these polymers typically lies between 1200 and 2000 cm³/10 min. This places particular demands on the testing system.

With the Mflow, ZwickRoell offers the right instrument to address this challenge. It enables the measurement of high MVRs, and with die plug ensures that the material stays in the extrusion barrel during preheating and that afterward, the test is automatically run with high quality.
