Synopex will begin production of nanometer (nm) class microfiber melt-blown (MB) filters for masks, the company said on Friday.

The company used its latest extrusion equipment for the 800nm non-woven fabric.

The fibers are thinner than those previously sold in South Korea, Synopex said, which allow for thinner holes in mask.

Synopex also applied polypropylene spinning technology to increase safety, it said.  

The filters will block ultra micro dusts and nm sized particles.

Synopex has been developing MB filters for 30 years. Filters used in semiconductor chemical-mechanical polishing is the best example. It can use its extrusion equipment to make MB filters for mask and protective clothing, as well as HEPA filters.

The company produces the MB filters at its Cheonan facility. Cheonan is used for air filters and its Pohang facility is for filters. Its Gimcheon factory produces MF, UF, NF membrane. Its Dongtan facility has its bio lab and focuses on research and development.

The company plans to supply high-performance, high-efficient e-PTFE and MB filters going forward.

Synopex recently filed a patent for melt-blown depth absolute filter, the second in the world to do so. The holes are 0.2 micrometers.
