SEKISUI CHEMICAL Achieves Progress in Creating PFAS-Free Pipes for Ultrapure Process Applications in the Manufacturing of Advanced Semiconductors
TOKYO, August 01, 2025--(BUSINESS WIRE)--SEKISUI CHEMICAL CO., LTD. (TOKYO: 4204) (President: Keita Kato; hereinafter "SEKISUI CHEMICAL") announced that, in response to the global trend of tighter regulations regarding perfluoroalkyl and polyfluoroalkyl substances (PFAS) and growing demand for reducing environmental impact, the Urban Infrastructure & Environmental Products Company (President: Yoshiyuki Hirai) had been developing a new technology for PFAS-free pipe materials for ultrapure process applications in the manufacturing of advanced semiconductors. As a certain level of progress has been established in the development of this technology, SEKISUI CHEMICAL will start to formally propose it to customers. 1. Background In the semiconductor and flat panel display (FPD) industries*, the ultrapure water being used needs to be supplied without lowering its water quality. The types of pipe materials for this purpose include those that use resin materials—hard polyvinyl chloride (PVC), polypropylene (PP), and fluorocarbon resins (polyvinylidene fluoride or PVDF, polytetrafluoroethylene or PTFE, and perfluoroalkoxy or PFA)—as well as those that use metallic materials in the form of metal pipes with special surface treatment. Today's advanced semiconductor industry, with the progress of ultra-miniaturization, requires pipe materials that can suppress the elution of inorganic and organic matter as far as possible. * The flat panel display (FPD) industry refers collectively to all industries related to the manufacture of flat panel displays, including liquid crystal displays, organic EL displays, and LED displays. 2. PFAS and Its Regulation PFAS refers to perfluoroalkyl and polyfluoroalkyl substances, which are difficult to break down in nature and may affect the human body or ecosystems. Among PFAS, the manufacture, import, and such of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) are already prohibited. As of now, PVDF, PTFE, and other materials used in fluorocarbon resin pipes and fittings for ultrapure process applications are not within the scope of regulation in Japan. However, in Europe and the United States, studies are being conducted to comprehensively subject PFAS to regulation. Together with other initiatives, there is a global trend of tighter regulations regarding PFAS. 3. Chronology of Development As a pioneer of plastic piping materials, SEKISUI CHEMICAL launched "Eslon Clean Pipe"—a hard PVC pipe material for transporting ultrapure water—in 1984. Since then, supported by an impressive track record, the product has been used in a wide range of applications. This time, a special olefin resin pipe material has been developed as a new low-elution material replacing fluorocarbon resins from the perspective of PFAS. In November 2022, a demonstration using an actual ultrapure water manufacturing system was started jointly with Kurita Water Industries Ltd. Compared to existing fluorocarbon resin pipe materials, this special olefin resin pipe material can reduce CO2 emissions during manufacturing by approximately 80%. Furthermore, in response to the global trend of PFAS regulation, SEKISUI CHEMICAL started working on developing PFAS-free pipes and fittings for ultrapure process applications. 4. Future Prospects With the establishment of this PFAS-free technology, SEKISUI CHEMICAL will start to formally propose it to customers and will aim for market launch within fiscal 2026. The company will also undertake development toward the early realization of creating valves, gaskets, and other pipe materials that are totally free from PFAS in the area of ultrapure process applications. SEKISUI CHEMICAL is accelerating the creation and market expansion of products—such as clean pipes—with high contribution to solving issues in the natural and social environments. For the realization of a sustainable society as well as sustainable growth as a company, the Products to Enhance Sustainability System is being promoted Group-wide to achieve ESG management at a higher level. SEKISUI CHEMICAL will seek to realize a sustainable society by 2030 through creating products that can contribute to solving issues in the natural and social environments when being manufactured as well as when customers use them.

Japan sees bright future for ultra-thin, flexible solar panels
Japan is heavily investing in a new kind of ultra-thin, flexible solar panel that it hopes will help it meet renewable energy goals while challenging China's dominance of the sector. Pliable perovskite panels are perfect for mountainous Japan, with its shortage of flat plots for traditional solar farms. And a key component of the panels is iodine, something Japan produces more of than any country but Chile. The push faces some obstacles: perovskite panels contain toxic lead, and, for now, produce less power and have shorter lifespans than their silicon counterparts. Still, with a goal of net-zero by 2050 and a desire to break China's solar supremacy, perovskite cells are "our best card to achieve both decarbonisation and industrial competitiveness," minister of industry Yoji Muto said in November. "We need to succeed in their implementation in society at all costs," he said. The government is offering generous incentives to get industry on board, including a 157-billion-yen ($1 billion) subsidy to plastic maker Sekisui Chemical for a factory to produce enough perovskite solar panels to generate 100 megawatts by 2027, enough to power 30,000 households. By 2040, Japan wants to install enough perovskite panels to generate 20 gigawatts of electricity, equivalent to adding about 20 nuclear reactors. That should help Japan's target to have renewable energy cover up to 50 percent of electricity demand by 2040. - Breaking the silicon ceiling - The nation is looking to solar power, including perovskite and silicon-based solar cells, to cover up to 29 percent of all electricity demand by that time, a sharp rise from 9.8 percent in 2023. "To increase the amount of renewable energy and achieve carbon neutrality, I think we will have to mobilise all the technologies available," said Hiroshi Segawa, a specialist in next-generation solar technology at the University of Tokyo. "Perovskite solar panels can be built domestically, from the raw materials to production to installation. In that sense, they could significantly contribute to things like energy security and economic security," he told AFP. Tokyo wants to avoid a repeat of the past boom and bust of the Japanese solar business. In the early 2000s, Japanese-made silicon solar panels accounted for almost half the global market. Now, China controls more than 80 percent of the global solar supply chain, from the production of key raw material to assembling modules. Silicon solar panels are made of thin wafers that are processed into cells that generate electricity. They must be protected by reinforced glass sheets and metal frames, making the final products heavy and cumbersome. Perovskite solar cells, however, are created by printing or painting ingredients such as iodine and lead onto surfaces like film or sheet glass. The final product can be just a millimetre thick and a tenth the weight of a conventional silicon solar cell. Perovskite panels' malleability means they can be installed on uneven and curved surfaces, a key feature in Japan, where 70 percent of the country is mountainous. - Generating where power is used - The panels are already being incorporated into several projects, including a 46-storey Tokyo building to be completed by 2028. The southwestern city of Fukuoka has also said it wants to cover a domed baseball stadium with perovskite panels. And major electronics brand Panasonic is working on integrating perovskite into windowpanes. "What if all of these windows had solar cells integrated in them?" said Yukihiro Kaneko, general manager of Panasonic's perovskite PV development department, gesturing to the glass-covered high-rise buildings surrounding the firm's Tokyo office. That would allow power to be generated where it is used, and reduce the burden on the national grid, Kaneko added. For all the enthusiasm, perovskite panels remain far from mass production. They are less efficient than their silicon counterparts, and have a lifespan of just a decade, compared to 30 years for conventional units. The toxic lead they contain also means they need careful disposal after use. However, the technology is advancing fast. Some prototypes can perform nearly as powerfully as silicon panels and their durability is expected to reach 20 years soon. University professor Segawa believes Japan could have a capacity of 40 gigawatts from perovskite by 2040, while the technology could also speed up renewable uptake elsewhere. "We should not think of it as either silicon or perovskite. We should look at how we can maximise our ability to utilise renewable energy," Segawa said. "If Japan could show a good model, I think it can be brought overseas." hih/sah/stu/lb Solve the daily Crossword
