Black fiberglass tissue is not typically used for medical equipment due to concerns about material safety, biocompatibility, and the potential for color-related issues in a medical context. Medical equipment often requires materials that are transparent or easily visible to ensure cleanliness and proper functioning. Additionally, materials used in medical applications must be non-toxic, resistant to corrosion, and able to withstand sterilization processes. While fiberglass can be used in some industrial applications, its use in medical equipment is limited and would require specific qualifications and approvals, focusing on white or clear forms that are more common in this industry.
