Fluoropolymer coatings are used in numerous industries, including: - Automotive parts - Semiconductor - Aerospace - Chemical industry - Medical and pharmaceutical - Food industry, among others Currently, a regulatory proposal is being considered within the EU to minimize the emissions of PFAS. ■ Target of the regulatory proposal Fluorine-based surface treatment agents: water and oil repellents, release agents, fluoropolymer-containing plating, etc. Coating materials: PTFE, PFA, FEP, ETFE, and other fluoropolymers (for applications such as corrosion-resistant lining, non-stick, lubrication, etc.) Molded and processed products: PTFE, PFA, FEP, ETFE, and other fluoropolymers (lining sheets, fabric sheets, etc.) Fluorine-based surfactants, fluorine-based oils, low molecular weight PTFE, fluorine-based molding aids, etc. The current regulatory proposal includes fluoropolymers, which are considered extremely stable and pose no toxicological or environmental concerns, and there is a possibility that fluoropolymer coatings may also be subject to regulation.

"The PFAS Countermeasures Guide for the Manufacturing Industry" is a comprehensive guidebook that consolidates essential information on the latest trends in PFAS and alternative technologies for 2025. It clearly explains the differences between PTFE, PFOS, and PFOA, which are surprisingly not well-known, through comparison tables detailing their structures, properties, and toxicity. Feel free to download it if you are interested. [Contents (excerpt)] ■ What are PFAS? ■ Latest trends in PFAS regulations ■ What should be done? Responding to regulations

PTFE (polytetrafluoroethylene) is the most widely used fluoropolymer and is also known by the brand name "Teflon." It is a material with properties such as non-stickiness, low friction, chemical resistance, weather resistance, excellent electrical characteristics, and high heat resistance (maximum operating temperature of 260°C). In response to trends in PFAS regulation, we are advancing the development of coatings using alternatives such as silicone and other engineering plastics as substitutes for PTFE (fluoropolymer). By appropriately adopting these alternatives according to their applications, it is expected that desirable functions can be achieved. 【Characteristics】 ■ Alternative technologies utilizing super engineering plastics such as silicone, PEEK, and PI ■ Non-fluorinated coatings optimized for specific applications ■ Functionality tailored to applications, such as release properties, non-stickiness, and chemical resistance 【Non-Fluorinated Coating Product Lineup】 Yoshida SKT continues to develop products in collaboration with customers, offering new non-fluorinated coating products as options to address next-generation challenges. Together with conventional products, we are realizing a diverse lineup of PFAS-free options. For more details, please download the materials or check the related links.

Among PFAS, PTFE (fluoropolymer) is a substance that has different properties from PFOS, PFOA, and PFHxS, which are regulated under international treaties (the POPs treaty). Unlike these substances, PTFE is considered to have no harmful effects unless used at significantly high temperatures. However, there is currently a proposal being considered within the EU to regulate a comprehensive range of PFAS, including PTFE. If this regulatory proposal is adopted, it could lead to international regulatory trends beyond the EU, so it is necessary to keep an eye on developments. If regulations on fluoropolymers become a reality, the impact on the manufacturing industry could be immense, forcing companies to seek alternatives. Since there is no technology that can completely replace the excellent functions of fluoropolymers, the response will be extremely challenging. Yoshida SKT offers both fluoropolymer coatings (Teflon coatings) and non-fluoropolymer coatings, providing proposals tailored to customer needs. For more details, please check the link.

Teflon is a trademark of Chemours and refers to fluoropolymer. Fluoropolymers include types such as PTFE, PFA, and FEP, but currently, the use of fluoropolymers like PTFE, PFA, and FEP is not regulated in Japan. On the other hand, within the EU, regulatory proposals are being considered to minimize the emissions of PFAS. The following substances are also mentioned as targets: - Fluorinated surface treatment agents: water and oil repellents, release agents, fluoropolymer-containing coatings, etc. - Coatings: PTFE, PFA, FEP, ETFE, and other fluoropolymers (for applications such as corrosion lining, non-stick, lubrication, etc.) - Molding and processed products: PTFE, PFA, FEP, ETFE, and other fluoropolymers (such as lining sheets, fabric sheets, etc.) - Fluorinated surfactants, fluorinated oils, low molecular weight PTFE, fluorinated molding aids, etc. The regulatory proposals include fluoropolymers, which are considered to be extremely stable and pose no toxicological or environmental concerns.
