High absorption thin millimeter-wave absorber (λ/4 type millimeter-wave absorption sheet)
Millimeter Wave Absorption Sheet "masa-sorb"
A thin, easy-to-process noise absorption and suppression sheet that can be adhered like a sticker. It can be adjusted to the specified frequency (approximately 20-100 GHz).
◆Millimeter Wave Absorption Sheet "masa-sorb" Sekisui Chemical has developed a radio wave absorber that can be adjusted to your specified frequency (approximately 20-100 GHz). It demonstrates high absorption across a wide bandwidth, primarily for automotive millimeter wave radar applications. This absorption sheet is thinner than conventional products, easy to process, and can be easily adhered like a seal. ◆Features Excellent radio wave absorption characteristics - High absorption - Wide bandwidth - High durability - Oblique incidence characteristics - High processability - Flexible, thin, and easy to apply - Punching processing available Differences from pyramid-shaped absorbers - Space-saving due to its sheet form and thinness - Contributes to cleanliness by preventing debris from falling due to impact or degradation (No falling of polyurethane foam or carbon powder)

Company information
The Sekisui Nano Coat Technology has developed a metal sputtering technology for fibers and commercialized it as the masa nano metal coating technology. Furthermore, this nano metal coating technology has been applied to various materials. Currently, this technology is also being applied to films. Additionally, our company originally started from the dyeing business for fabrics and is now involved in dyeing and raising processes for synthetic leather base materials used in automotive, railway, and aircraft-related seats, as well as shoes, bags, and interiors. We respond to various requests with processes such as dyeing, raising, and flame retardant treatments.
