Membrane/Filter BUSINESS

Mask Filter


SYNO.TEX helps manufacturers or users separate the bad from the good in the air or liquid like water and chemicals.
SYNO.TEX is highly homogeneous pore-sized membrane due to Synopex’s high-tech expanding process. It is produced from PTFE fluoroplastic that has high water-repellency, no-toxic and heat-resistant property.

e-PTFE Membrane (SYNO.TEX) is applied to the filter product materials in various industrial fields like as fuels cells, HEPA/ULPA high-functional air filters, separation membranes, artificial blood vessel, semi-conductor, pharmaceutical and bio industries.
We provide high-performance filters for mask with safety and comfort.
SYNO.TEX Features
