Ceramic fiber cotton is an insulating material composed of ceramic fibers, known for its lightweight, high temperature resistance, and thermal insulation properties. During the manufacturing process, ceramic fibers are formed into a continuous and flexible fiber structure using special techniques. In traditional applications, ceramic fiber cotton is commonly used for thermal insulation linings in high-temperature furnaces and insulation of pipelines. In the new energy industry, ceramic fiber cotton plays a crucial role, especially in the application of new energy electric vehicles. In the field of electric vehicles, ceramic fiber cotton is widely used for thermal insulation protection of battery packs, effectively preventing the adverse effects of high temperatures on battery performance. Its excellent insulation performance and high temperature resistance make it an indispensable thermal insulation material in new energy electric vehicles, providing a reliable solution to enhance the safety and performance of battery systems.
