Recently, Arkema announced that nanofiber masks made with its Kynar® PVDF have come out. The core filter element of this mask is KN95 based on Kynar® PVDF material and a special filter element for medical masks, which is jointly created with Chinese nanofiber filter material manufacturer JSNY Nanofiber Technology Company. Longer days of use!
This mask consists of a non-woven fabric layer, a nano-fiber layer and a melt-blown fabric layer. The nanofiber layer made of Kynar® PVDF serves as the main filter layer.
Compared with ordinary N95 masks, the nanofiber mask produced by Nayi will have a finer fiber diameter. The diameter of ordinary melt-blown PP fiber is up to 5000 nanometers, and the diameter of the PVDF nanofiber layer under the observation of scanning electron microscope is only 100 nanometers. It significantly improves the filtering efficiency of the mask.
In addition to excellent filterability, the outstanding properties of Kynar® PVDF also extend the life of the mask. Normal masks have a shelf life of 2 years, while Kynar® PVDF masks have a shelf life of up to 5 years.
The Kynar® PVDF material used for this nano-grade mask, Kynar® PVDF was commercialized in 1965 and has a history of nearly 55 years. Kynar® PVDF has excellent comprehensive performance and durability, and is proven in a variety of harsh industrial applications around the world, from high-performance outdoor architectural coatings, offshore oil production pipes, industrial sewage and municipal sewage water treatment filters, solar backsheets Membrane, ultrapure water piping system to semiconductor production, etc.
The applications of Kynar® PVDF are constantly expanding, from lithium batteries on smartphones and electric cars, to water filter membranes for home use, from durable sports socks to masks for epidemic prevention.
