Tokyo, Japan – July 18, 2025 - AGC (AGC Inc., Headquarters: Tokyo; President: Yoshinori Hirai), a world-leading
manufacturer of glass, chemicals and other high-tech materials, proudly announces the launch of surfactant and
fluorinated polymerization solvent free grades in its fluoroelastomer “AFLAS™ FFKM” series; the SF grades (the
“Products”). The newly developed Products are manufactured entirely without the use of any surfactants*1 or
fluorinated polymerization solvents*2. The Products offer high performance equivalent to that of conventional
products, while meeting the growing market demand for fluoroelastomers that do not use surfactants or fluorinated
polymerization solvents during the manufacturing process. This has been achieved through AGC’s innovative,
proprietary polymer manufacturing technology (Surfactant-Free & Fluoro Solvent-Free Technology, hereafter the
“Technology”). Initially, this Technology will be applied to the high-temperature-resistant type of FFKM
fluoroelastomers and new grades will be added to the “AFLAS™ FFKM” series for semiconductor manufacturing
equipment. Commercial availability of this new grade begins this month. We are planning to extend the Technology
to other types of FFKM fluoroelastomers and will progressively introduce those new types of Products as part of
“AFLAS™ FFKM” series.
The “AFLAS™ FFKM” series is an industrial elastomer that offers one of the highest levels of resistance to
chemicals, heat, and plasma among fluoroelastomers. Its outstanding properties make it exceptionally durable
even in harsh environments such as semiconductor manufacturing, oil drilling, and healthcare. In particular,
“AFLAS™ FFKM” is recognized as an essential material in the etching process, one of the key steps in
semiconductor manufacturing, due to its exceptional plasma resistance. Its resistance to degradation makes it an
ideal sealing material for etching equipment, where it contributes to significantly extended maintenance intervals
and enhanced operating safety.
Previously, surfactants and fluorinated polymerization solvents were considered essential for manufacturing high
performance fluoroelastomers, FFKM, due to their roles in enhancing the reactivity of fluorinated monomers and
manufacturing efficiency. In recent years, however, customers’ demand for products that do not use these
substances during the manufacturing process have grown rapidly, particularly in the semiconductor industry.
While various approaches without using surfactants or fluorinated polymerization solvents have been explored,
achieving the high-performance requirements of FFKM was a significant challenge.
To meet this market demand, AGC has successfully overcome this long-standing technical challenge and
succeeded in mass-production of the Products by applying the new Technology, which does not require the use of
any type of surfactants or fluorinated polymerization solvents, which has been developed by refining our unique
polymerization technology cultivated over many years. Accordingly, AGC is now proud to introduce the Products
as new addition to its AFLAS™ FFKM series.
Under its corporate philosophy of “Look Beyond” , the AGC Group is committed to supporting the lives of
people around the world through its unique materials and solutions. Going forward, we will continue to contribute
to the realization of a safe, secure, and sustainable society through our high-performance, high-quality materials.
Notes
*1 surfactant: A chemical substance used to mix non-mixable substances and form a homogeneous mixture called
an emulsion. Also called an emulsion.
*² polymerization solvent: A solvent used to promote polymerization reactions. Various solvents are selected
depending on the type and purpose of polymerization. In emulsion polymerization, water is generally used,
while in solution polymerization, solvents that easily dissolve the polymerizable monomer are used.
