"Heat resistant" refers to materials or substances that can withstand high temperatures without deforming, melting, or losing their structural integrity. These materials are often used in various applications, such as cookware, industrial equipment, and protective clothing. Common heat-resistant materials include ceramics, metals, and certain types of plastics. The ability to resist heat is crucial in many industries, including aerospace, automotive, and construction. For example, firefighters wear heat-resistant gear to protect themselves from extreme temperatures while battling fires. Understanding heat resistance helps in selecting the right materials for specific tasks, ensuring safety and efficiency.
