A Chinese technology company, Safmax, has revealed a new kind of nano-membrane fabric that can survive extreme heat up to 2,192°F (1,200°C) without melting, shrinking, or losing shape.
The new material was introduced at the China Public Security Tech Expo and is being described as a fireproof and safety fabric. The company says this new material is fireproof, waterproof, windproof, and breathable, making it one of the most advanced protective textiles ever made.
During the presentation, Safmax engineers explained that the fabric is very light and strong. Unlike the traditional heavy flame-retardant suits that firefighters wear, manufacturers can use this fabric on fibers as thin as one percent the width of human hair. That makes it soft, flexible, and easy to move in, even while providing strong protection against heat and fire.
Safmax says this new material will change fire protection gear. Normal protective suits are often heavy because manufacturers make them with many layers and treat them with different chemicals. This new nano-membrane material changes that by combining multiple protective layers into a single layer.
“This is not just a heat-resistant fabric,” said Jiang Huangsen, the Chief Technology Officer of Safmax. “It’s a next-generation shield against fire hazards. It protects people while keeping them comfortable and mobile.”

He added that it could also help prevent fires from spreading by isolating air during a battery explosion, which is becoming more important as electric cars become more common.
At the Expo, Safmax performed a live test to show the fabric’s special qualities. The company demonstrated that water could not pass through the nano-membrane, but air could still flow out easily. This means the fabric is waterproof and windproof but still breathable.

“This is a very effective and convenient solution to fight fires,” said one of the engineers during the event. “It’s light, it’s strong, and it can work even in extreme temperatures.”
The company did not share the exact chemical composition of the fabric, but experts say it is based on advanced nanotechnology that forms a thin but powerful protective layer.
In the past, manufacturers made flame-retardant fabrics using materials like phytic acid (PA), ammonium polyphosphate (APP), or diphenylphosphine (DPP). These chemicals worked by making the fabric char instead of burn, or by releasing gases that suppress flames.
Manufacturers today make most firefighter uniforms from multi-layered fabrics such as Nomex and Kevlar, which provide heat resistance and strength. They also include a moisture barrier and a thermal layer to block water and provide insulation. However, these suits can be bulky, making it harder for firefighters to move quickly.
Safmax’s fabric offers the same level of protection in a much thinner and lighter layer. Jiang said that manufacturers can add the new nano-membrane coating to normal fabric while keeping it thin, breathable, and flexible. “They can apply it to regular cotton or synthetic fibers and it will still perform at the highest level,” he explained.
Safmax believes its fabric can be used far beyond firefighting. It could help protect workers in industrial plants, refineries, and factories operating at high temperatures. It could also play a role in aerospace, military, and energy industries where workers need both heat protection and mobility.
