China’s new carbon nanotube insulation can resist temperatures exceeding 4,700°F

Chinese researchers have created a carbon nanotube film that withstands temperatures up to 4,712°F (2,600°C), outperforming conventional insulators. This lightweight material blocks all heat transfer types and exhibits exceptional thermal resistance. Composed of stacked, super-aligned carbon nanotube sheets, it has a low conductivity of 0.03 W/mK at extreme temperatures. Flexible and scalable, this innovation could revolutionize aerospace, energy, and manufacturing industries with superior high-temperature insulation.
