Stedelijk Museum Amsterdam Modern Wing Featuring
Teijin-supported Large-scale Composite Facade
Celebrates 10th Anniversary
Tokyo, Japan, September 30, 2022 --- Teijin Limited announced today that the modernwing of the Stedelijk Museum Amsterdam featuring the world’s largest composite facade,made with Teijin Group’s Twaron® para-aramid fiber and TenaxTM carbon fiber, iscelebrating its 10th anniversary this year. Teijin, which operates group companies in
Europe under a regional headquarters located in Amsterdam, has been sponsoring themuseum since 2007 as a cultural initiative inspired by the company’s philosophy ofgrowing and evolving in harmony with society.

Cross section of the facade

The design by Benthem Crouwel Architects was soon widely known as the “bathtub” dueto its distinctive shape, features a smooth, seamless and shiny white facade and canopy
incorporating 185 composite panels madewith the Teijin Group's Twaron® andTenaxTM

advancedfibermaterials.

Measuring 100 meters by 25 meters andseemingly floating in the air, this world’s
largest composite facade is a striking
contrast to the museum’s original neorenaissance building. Thanks to the designthat keeps out rain and dirt and the use ofTwaron® and TenaxTM, this building proves
to be practically maintenance-free, making
it a sustainable construction that canTeijin brand logo projected on the “bathtub”

reduce maintenance costs since opening in 2012 to the present. In addition, the smoothand pristine surface of the “bathtub” lends itself perfectly to projections of, among otherthings, video art, which amazes citizens and visitors from all over the world.
It was known that very large building components would be required to produce thefacade, but this presented potential problems due to the thermal expansion and distortionof the components over time. Conventional building materials were rejected, but after anumber of verifications were performed the builders selected resin-coated sheets madewith a combination of Twaron® and TenaxTM, which minimize the effects of thermal
expansion thanks to the fibers’ strength and low coefficients of thermal expansion.
Twaron® para-aramid fiber produced by Netherlands-based Teijin Aramid B.V. andTenaxTM carbon fiber produced by Teijin Carbon Europe GmbH in Germany werecombined with vinylester resin in composite laminates, forming the outer skins of acomposite sandwich construction with a core of PIR foam. Whereas resin expands as
the temperature rises, both Twaron® and TenaxTM fibers actually contract, therefore
ensuring minimal expansion of the panels to realize a seamless look while creating
significant structural stability. Unlike structures made with glass, metal or glass fiber
composites, the ingenious design of the “bathtub” become a reality through the uniqueproperties of Teijin’s high-performance fibers, creating a high-profile architecture in thecenter of Amsterdam.
Going forward, Teijin will continue to grow together with local communities and provide
products and services that contribute to a more sustainable world.
