At China’s second Public Security Tech Expo in Lianyungang, Safmax introduced advanced fabrics that reportedly withstand extreme heat while staying breathable, waterproof, and windproof, according to an 18 September article by Interesting Engineering.
Safmax says its flame-resistant fabric can endure temperatures up to 2,192°F (1,200°C) without melting, shrinking, or losing shape. The fabric protects firefighters, shields with fire blankets, and controls airflow during battery fires in electric vehicles.
Nano-Membrane Fabric: Waterproof Yet Breathable
Jiang Huangsen, Safmax’s chief technology officer, said the company applies its nano-membrane to regular fabric at a thickness just 1% that of a human hair. In a demonstration, the material blocked water while allowing air to pass, making it both waterproof and breathable.
Interesting Engineering explains that manufacturers typically make flame-retardant fabrics by using naturally resistant fibers or chemically treating flammable materials.These methods protect the fabric by charring it, releasing gases that suppress flames, or forming an insulating barrier.
Traditional firefighter gear uses multiple fabric layers, including aramid fibers, moisture barriers, and quilted thermal layers, to resist heat, flames, and moisture.
Safmax positions its fabrics as a practical and effective option for extreme fire safety, building on advances in flame-retardant cotton and nano-membrane technology, the article added.
