Thermal degradation is the process where materials break down due to exposure to high temperatures. This can lead to changes in the physical and chemical properties of the material, often resulting in loss of strength, color, or functionality. Common examples include the breakdown of plastics and rubber when heated excessively. This phenomenon is important in various fields, including materials science and engineering. Understanding thermal degradation helps in selecting appropriate materials for applications that involve heat, such as in automotive or aerospace industries, where durability and performance are critical.
