Ceramic fiber products are generally not used for medical equipment and instruments due to their composition and properties. These products are typically made from materials like alumina silicate and are used in high-temperature applications such as insulation in industrial settings. Medical equipment and instruments require materials that are biocompatible, non-toxic, and resistant to sterilization processes. Materials used in medical devices include stainless steel, titanium, and various plastics that meet strict safety and performance standards. Therefore, ceramic fiber products are not suitable for medical applications.
