Aerogel, often referred to as "frozen smoke," is a highly porous material that provides exceptional thermal insulation. Its low density and high thermal resistance make it an excellent choice for applications requiring superior insulation with minimal added weight. Aerogels are used in aerospace, building insulation, and high-performance electronics where space and weight are critical factors. Despite its fragile appearance, aerogel can be reinforced with other materials to enhance its mechanical strength, making it a versatile option for advanced thermal management solutions.
