Non-Woven Polymer Nanofabric

Polymeryx was a partner in the design and development of the ViraShield Tm product line.  The material is a non-woven electrospun polymer. Leveraging Polymeryx' extensive polymer processing experience with electrospinning, they partnered to create a nanofabric designed to capture particles down to 0.1μm with an average filtration efficiency of 99.969%, in accordance with ASTM F2299. 

 

This filtration material is certified for medical use under ASTM F2100.  This is a novel high-performance fabric created for microfiltration.

​

Electrospun nanofiber exhibit uniques properties:

​

• High porosity

• Large surface area to Volume ratio

• High degree of interconnection

• Modifiable functionality

​

The manufacturing is monitored and controlled for:

• Morphology

• Apparent density

• Porosity

• Contact-angle

• Pore size distribution

• Flux & filtration efficiency

​

The bacterial filtration efficiency and differential pressure complies with ASTM F2100-19.
