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. The traditional heavy flame-retardant suits that firefighters wear, this fabric can be used on fibers that are 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 they are made of many layers and treated with different chemicals. This new nano-membrane material changes that by combining multiple protections in 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 stop fires from spreading by isolating air during a battery explosion, something that is becoming more important as electric cars become 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, flame-retardant fabrics were made 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.
Most firefighter uniforms today are made 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 the new nano-membrane coating can be added to normal fabric while keeping it thin, breathable, and flexible. “It can be applied on regular cotton or synthetic fibers and 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 that deal with high temperatures. It could also play a role in aerospace, military, and energy industries where both heat protection and mobility are needed.
