Shin-Etsu Polymer chooses Solvay’s KetaSpire® PEEK to meet growing demand for its ultra-thin, high-performance film
TOKYO, Japan, June 19, 2017– Solvay, a leading global supplier of specialty polymers, is supplying KetaSpire® PEEK (polyetheretherketone) to Shin-Etsu Polymer for the manufacture of its ultra-thin, high-performance Shin-Etsu Sepla Film®, with thicknesses ranging from 3-9 µm (0.11-0.35 mils), which is widely used in speaker diaphragms for mobile devices and loudspeakers, and other related consumer goods such as headphones and microphones.
“KetaSpire® PEEK’s unique combination of excellent mechanical properties, high temperature tolerance, high purity, flame retardancy, and superior resistance to wear, abrasion and fatigue meets the stringent performance requirements for Shin-Etsu Sepla Film®,”says Kazuhiro Kiroko, Managing Director for Solvay Specialty Polymers Japan K.K. “Also, the processing ease of Solvay’s PEEK has enabled Shin-Etsu Polymer to optimize its fabrication process and develop a broad range of grades and gauges to help boost market end-use growth.”
Thanks to its ability to minimize acoustic output distortion and suitability for post-lamination, Shin-Etsu Sepla Film® is already used extensively in speaker diaphragms in smartphones and other mobile devices. “Consumers are demanding better sound quality, and our ultra-thin film helps optimize acoustic performance through more effective resonance concerning volume and loudness,”says Katsuhiko Seriguchi, Director GM, Group II Sales & Marketing Division IV at Shin-Etsu Polymer. “Our ultra-thin film technology is also being used to develop and grow end-use applications in other industrial market segments.”
Shin-Etsu Polymer’s advanced technology allows the manufacture of non-stretched Shin-Etsu Sepla Film® in gauges ranging from 3-50 μm (0.11-1.96 mils) to 6-50 µm (0.23-1.96 mils) with low and high crystallization, respectively. The company also manufactures films with thicker gauges of up to 250 µm (9.84 mils) to meet specific customer requirements. In response to growing demand for high-performance polymer film, Shin-Etsu Polymer installed new equipment to expand capacity at its Tokyo plant (Saitama City) and offer film with widths ranging from 650-1300 mm (25.5-51 inches).
Shin-Etsu Sepla Film® is also suitable for applications in a wide range of industries that include electrical wiring insulation and other insulative applications such as in cable wrapping, automotive components, electronic circuit boards, aerospace, robotics, and medical devices. Because of its high-temperature performance, Shin-Etsu Sepla Film® can be used as a masking material for lead-free soldering in electronic applications.
