Development of a Highly Breathable, High-Barrier Nanofiber Sheet — PFAS-Free

Only 8.5 Pa: Ultra-Low Pressure Loss Nanofiber Sheet, Achieved Without PFAS

Technical Fine’s nanofiber sheet is a next-generation material designed without the use of PFAS, anticipating future environmental regulations.
Compared with conventional mask filters, it achieves approximately one-third of the air resistance (8.5 Pa), delivering excellent breathability while effectively suppressing water droplet penetration to the reverse side.

Through a precisely controlled nanofiber structure, this solution balances comfort (low pressure loss) and safety (high barrier performance).

Allows Air to Pass, Resists Water — The “Ideal Barrier” Created by Nanofibers

This sheet is designed to reliably repel water droplets on the surface while preventing moisture penetration, all while allowing air to flow smoothly through the material.
By achieving both water repellency and breathability without PFAS, it simultaneously delivers high performance and reduced environmental impact.

Its applications are expected to expand beyond masks and filters to a wide range of industrial products.
