Medical surgical masks developed by Ascend reach level III protection

Houston – July 14, 2020 – Ascend announced that it has filed a 510(k) Premarket Notification (PMN) with the U.

Ascend's medical surgical masks based on Acteev™ technology reach level III protection and can effectively kill SARS-CoV-2

This series of masks belongs to the Acteev Biodefend™ medical product series, including two non-woven versions of nanofiber and microfiber, reaching the highest protection level of 510(k), effectively killing viruses, and resisting microorganisms, aerosols, liquid splashes, etc.

Ascend Chief Technology Officer Dr.

This series of masks has been tested by an independent laboratory and a team of Ascend scientists and certified to meet the level III protection level under the ASTM F2100-19 standard

Dr.

Some masks achieve filtration and barrier effects through electrostatic adsorption of materials, and when antimicrobial agents are added, these materials will lose their charge and the protection will fail

The Acteev™ technology achieves antiviral effect by embedding active zinc ions in the PA66 polymer matrix

"Acteev™ is the code that balances physical barrier properties with antiviral properties for superior protection

Acteev™ technology covers more than 15 patent families and has been tested in a variety of finished product formats, including knitted and woven fabrics, engineering plastics, as well as nanofiber, meltblown and spunbond nonwoven materials

Ascend submitted its first 510(k) product listing application to the FDA last month, a Class I medical surgical mask based on Acteev™ technology that provides effective protection against SARS-CoV-2

Ascend also launched Acteev Protect™ antimicrobial fiber technology last month, a breakthrough technology designed to inhibit the growth of mold, fungus and other microorganisms, enabling long-lasting, safe, antibacterial and cleaning of textiles and nonwovens

About ActeevTM

●Tests have proved that it can effectively kill viruses, bacteria and fungi, with an efficacy of more than 99%

●Zinc ion intercalation polymer that meets EPA standard requirements

The hygroscopic PA66 fabric absorbs moisture, thereby activating zinc ions

● No topical treatment or coating

● not dependent on silver or copper

● Plays a significant role in a variety of finished forms:

◦ Knitted and woven fabrics for consumer textiles, home, workwear, masks, etc.

◦ Nanofiber, meltblown and spunbond nonwoven materials for filtration

◦ fibers for carpets

◦ Engineering plastics for high-touch surfaces
