Kurita and Sekisui Chemical: Pioneering PFAS-Free Solutions in Semiconductor Manufacturing

In recent years, the semiconductor industry has faced increasing scrutiny regarding the use of per- and polyfluoroalkyl substances (PFAS), which are man-made organic fluorine compounds known for their water- and oil-repellent properties. As regulations tighten around the globe, including Japan's upcoming water quality standards set for 2026, Kurita Chemicals, headquartered in Nakano, Tokyo, has taken proactive steps to address the use of PFAS in ultra-pure water systems. Collaborating with Sekisui Chemical, they have aimed to develop piping systems that are free from harmful organic fluorine compounds.

PFAS has been widely utilized across various sectors due to its excellent chemical resistance and heat tolerance. Unfortunately, certain types of PFAS have been associated with health risks, including cancer and negative impacts on child development. This has prompted stricter regulations and the need for alternative materials that do not compromise safety or performance. The Kurita group recognizes the urgent societal challenges posed by PFAS and has committed to analyzing the compound's impact while providing solutions for its detection and treatment to customers.

In their endeavor to create PFAS-free materials for ultra-pure water systems, Kurita has engaged in extensive collaboration with Sekisui Chemical's Environmental and Life Line Company. The companies have explored a novel polymer developed specifically to replace traditional organic fluorine resins, such as polyvinylidene fluoride (PVDF). Early testing indicated promising results, achieving comparable performance levels in terms of leachability and particle emissions while pushing forward with improvements regarding PFAS.[1]

A major focus of this collaboration centers on the demands of the semiconductor manufacturing sector, where ultra-pure water is critical. The newly engineered opaque olefin resin, specifically designed for low leachability, has shown potential to meet the industry's evolving needs. Since November 2022, tests at Kurita’s Innovation Hub (KIH) have demonstrated that the new piping and fittings align with the performance parameters established for PVDF, making significant strides towards fully realizing PFAS-free solutions.

Looking ahead, Kurita aims to broaden the scope of their testing, targeting the integration of PFAS-free ultra-pure water materials into water purification equipment across a range of users, including those internationally. This initiative extends beyond semiconductor manufacturing to include water treatment systems for various applications, encompassing a broader goal of facilitating a PFAS-free environment across multiple industries.

As a company that has been dedicated to water-related solutions since its inception, Kurita continues to leverage its expertise to innovate and offer sustainable technologies and products. By addressing critical environmental issues successfully, Kurita aspires to contribute to the realization of a sustainable society through ongoing efforts in developing a comprehensive range of PFAS-free materials.

In summary, the collaboration between Kurita and Sekisui Chemical marks a pivotal advancement in addressing the pressing challenges posed by PFAS in ultra-pure water systems within semiconductor manufacturing. By introducing alternatives that are both safe and effective, these companies are setting industry standards while underscoring their commitment to sustainability and public health.
