polyurethane water repellent
Fluorine free polyurethane waterproofing agent is an environmentally friendly fabric finishing agent mainly composed of polyurethane polymers and free of perfluorinated compounds (PFAS). It forms a cross-linked hydrophobic membrane by reacting the active groups at the end of the molecular chain (such as - NCO, - OH) with the polar groups on the fiber surface, thereby achieving waterproof function. Compared to traditional fluorinated waterproofing agents, its core advantages lie in:
Environmental friendliness: Compliant with the EU REACH regulation and China's Key Control New Pollutant List for the prohibition of PFAS, with a biodegradability of over 90% (OECD 301B standard).
Performance balance: By introducing organosilicon or long-chain alkane modification, the static water contact angle can reach 130 °~140 °, and the washing resistance can reach 20~30 times (AATCC 22 standard), approaching the level of fluorine-containing products.
Core application areas
High end outdoor equipment: Nylon fabric used for assault jackets and mountaineering tents, which combines waterproofing (water pressure resistance ≥ 10kPa) and breathability (moisture permeability ≥ 5000g/m ² · 24h).
Medical protective material: Composite with polypropylene meltblown fabric, meeting the requirements for liquid barrier in the GB 19082-2020 standard for medical protective clothing.
Automotive interior: Enhance the stain resistance of seat fabrics without releasing harmful gases (detected by VOC).
