Fluororesin Products for PFA lined ball valve, Insertion pipe, safety valve, pressure gauze, gasket, and etc. for use of transportation of chemical solution in semiconductor devise and liquid crystal factory. 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 PFA in Daikin Industries This product is to be used under the following conditions. Subject to use: PFA lined ball valve, Insertion pipe, safety valve, pressure gauze, gasket, and etc. for use of transportation of chemical solution in semiconductor devise and liquid crystal factory Fluid to be used: Unspecified due to wide variety Usage Environment: RT60 Use Conditions: Not to be affected by fluids in the use environment and no leakage. No elution of metal ions in chemicals There is no perfect replacement product at the moment since they are required to be chemical-resistance for fluid and not to extract metal ions for chemical solution. Reference: Plastic Data Handbook, VALQUA Handbook Technical Section, Kogyo Chosakai Publishing Co., Ltd. As mentioned above, the presence of fluororesin product is essential for transport container of high purity chemical solution for semiconductor. We propose a regulatory exemption for the above reasons. Attachment 1: PTFE Safety Date Sheet r FDA IKt~ Printing date 06.02.2023 Safety data sheet Version number I 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-12, 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.
