Ceramic fiber products are generally not used in medical equipment due to their composition and properties. These fibers are known for their heat resistance and thermal insulation, which makes them suitable for industrial applications such as furnace linings and heat shields. However, in the medical field, materials must be biocompatible and non-toxic. Ceramic fibers can potentially cause irritation or other adverse reactions if they come into contact with human tissue. Therefore, they are not typically incorporated into the design or manufacturing of medical devices. Instead, materials like stainless steel, plastics, and certain biocompatible metals are preferred for their safety and reliability in medical applications.
