SummarySummary• MBNW is widely applied and has a large potential as the filter media.• Fiber diameter and its distribution of MBNW strongly influence the filtration• Fiber diameter and its distribution of MBNW strongly influence the filtration
performances.• The suitable selection of raw material is also key factor for filter design.
F th i i t f MBNW li th f ll i th k• From the view point of MBNW supplier, the followings are the key technology.
+The control of fiber diameter and its distribution+MBNW forming of the various thermoplastic raw material+Effective and durable electret method
• Tapyrus will continue the MBNW development for the filtration industry. py p y
