Application Number:E.2.1 (Manufacture) Fluororesin Products for Manufacturing Processes of Various Fluoride Gases Lining tank (PTFE), lining piping (PTFE, PFA), lining valve (PTFE, PFA), insertion tube (PTFE, PFA), gasket (PTFE), bellows (PTFE, PFA) Flexible hose (PTFE, PFA), pliable hose (PTFE, PFA) PFAS used in the products is PTFE and PFA, which are polymer materials, and there is no concern about exposure, leakage, or environmental release of eluates. (Reference: SDS of PTFE in Daikin Industries, SDS of PFA in Daikin Industries) This product is to be used under the following conditions. Subject to use: Wetted parts of piping systems in various fluoride gas manufacturing processes Fluid to be used: anhydrous hydrogen fluoride, hydrofluoric acid Usage Environment: RT to 150C Use Conditions: Not to be affected by fluids in the use environment and no leakage. No elution of metal ions in chemicals Required to meet the above specification conditions, and no perfect alternative product is considered to be available at this time, (Reference: Plastic Data Handbook, VALQUA Handbook Technical Section, Kogyo Chosakai Publishing Co., Ltd.) As mentioned above, the presence of fluororesin product is essential for chemicals used in manufacturing processes of various fluoride gases. We propose a regulatory exemption for the above reasons. Attachment 1: PTFE Safty Date Sheet rDAIKIN Printing date 06.02.2023 Safety data sheet Version number 1 Page 1/6 Revision: 06.02.2023 SECTION1: Identification of the substance/mixture and of the company/undertaking 1.1 Product identifier Trade name: POLYFLON PTFE M-I2, 18, 18F, 391S, 392, 393 Article number: M 1.2 Relevant identified uses of the substance or mixture and uses advised against: No further relevant information available. 1.3 Details of the supplier of the safety data sheet Manufacturer/Supplier: DAIKIN INDUSTRIES, LTD.
