Application Number: E.2.9 (medical devices) Fluororesin used: PTFE (CAS No. 9002-84-0) Product Overview: endoscope cable Fluororesin is used in cables for medical devices and cables of endoscope. The application requires properties such as flexibility, insulation properties, and purity, and fluororesin is employed as a member satisfying required specifications. For example, for flexibility, the use of other polymer materials causes a quality risk for cables as the other polymer materials do not have sufficient properties for the required thickness. As mentioned above, no alternative products have been found at this time because other polymer materials do not have sufficient properties and affect quality. We believe that the regulatory exemption for this application from proposed restriction is reasonable. Representative properties of fluororesin are shown in the following table.
