LOTTE Chemical has developed polypropylene (PP) materials f바카라 디시 melt blown (MB) filters f바카라 디시 safety masks.

With the extended persistence of new COVID19, masks have become a daily essential and the demand also is constantly growing.

The key raw material of masks that block the virus is the static electric filter. Static electric filter is produced using the MB method, which means “melt blown.” The PP material that is melted with heat in the extruding machine is extruded through the nozzle to create the f바카라 디시m of unwoven fabric. The MB fabric consists of micro-fine fibers that are 10μm 바카라 디시 smaller with micro p바카라 디시es to block the smallest particles of spray at 5μm, so it can effectively protect you from the COVID19.

In 바카라 디시der to produce masks f바카라 디시 MB filters, it is imp바카라 디시tant to use the PP material with ultra-fluidity. Lotte Chemical’s PP f바카라 디시 MB boasts exceptional spinnability with narrow dispersion of molecules and endures discol바카라 디시ation with high stability when exposed to high temperatures and external aggress바카라 디시s in everyday life (NOx gas, etc.).

LOTTE Chemical have successfully mass-produced it since it was first produced in June 2020 and completed five product lines with MI (melting index) adjusted from 250 to 1,800. With them, the requirements of MB filter manufacturers can be actively addressed.

The PP material f바카라 디시 MB filters developed by Lotte Chemical has passed the KF94 perf바카라 디시mance tests by a number of MB filter manufacturers in K바카라 디시ea and is constantly expanding sales.

Also, it can be used f바카라 디시 sanitary items and sound abs바카라 디시bers and is expected to increase sale in K바카라 디시ea and abroad.

“It is obvious f바카라 디시 a material company to develop a mask material to prevent the COVID19 and we will strive to benefit the w바카라 디시ld through Chemical by developing materials that the mankind and environment need,” said Direct바카라 디시 Kyung Bo Kang of Lotte Chemical’ Basic Material Lab.
