Original PLEXIGLAS® displays its strengths not only in terms of aesthetics, but also when it comes to acoustics. PLEXIGLAS® Soundstop is a special product that protects against noise and is also used on bridges as effective protection against wind.
Solid PLEXIGLAS® Soundstop sheets feature outstanding airborne sound insulation properties while also offering the highest degree of transparency. This transparency remains intact for a very long period of time. We guarantee that PLEXIGLAS® Soundstop will display virtually no signs of yellowing even after 30 years of permanent use.
In addition, PLEXIGLAS® Soundstop sheets
PLEXIGLAS® Soundstop is used for noise and wind protection screens along traffic routes, enclosures and bridges. In order to satisfy a wide range of requirements, the innovative sheets are available in various visually appealing varieties and with special properties, such as:
PLEXIGLAS® Soundstop XT BirdGuard reliably protects against birds, while also providing maximum transparency. This variety features 2 mm-wide black or white strips spaced 30 mm apart, which are perceived as a visible obstacle by birds. Because the strips are embedded within the material, they cannot be washed away by cleaning agents or graffiti removers.
PLEXIGLAS® Soundstop GS CC also provides integrated shatter protection thanks to the embedded polyamide threads. These threads bind together the fragments and prevent them falling in the event that a sheet is broken. PLEXIGLAS® Soundstop GS CC is approved around the world for use as a transparent material for noise protection walls on bridges without additional nets.

In December 2022, Röhm, supported by the private equity firm Advent International, agreed to acquire SABIC's Functional Forms business unit, which specializes in polycarbonate-based films and sheets sold under the LEXAN™ brand.
This strategic move aimed to enhance Röhm's position in the transparent films and sheets market by combining SABIC's polycarbonate products with Röhm's existing polymethyl methacrylate (PMMA) offerings, known under the PLEXIGLAS® (ACRYLITE® in the Americas) brand.
By November 2023, Röhm and SABIC announced plans to merge Röhm's Acrylic Products and SABIC's Functional Forms business units into a new entity named Polyvantis.
This new company, POLYVANTIS, aims to become a leading supplier of film and sheet products, serving various industries such as building and construction, transportation and aviation, electrical and electronics, automotive, and home and garden. Polyvantis is expected to have approximately 1,500 employees and operate 16 production sites across the Americas, Europe, Asia, and Africa.
