Solvay & Tosaf: UV light stabilization for stadium seating

Annually, millions of outdoor sports fans around the world cheer on their favorite teams from their stadium seats. Typically, these outdoor seats are exposed to all kinds of weather conditions throughout the year. Selecting the proper UV light stabilization package is therefore critical to prolong the lifetime of stadium seats. 

Tosaf, one of Solvay’s customers, is a leading, global, one-stop-shop manufacturer of high-quality color and additive masterbatches and compounds for the plastics industry. Solvay provides Tosaf with UV light stabilizers for various end applications, including outdoor stadium seats. Both companies share a focus on innovation, continuing to provide the market with specific, advanced formulated solutions. 

Through ongoing collaboration, Solvay and Tosaf are attempting to extend the durability of plastics and, therefore, improve their sustainability profile by extending product service life.

“We work closely with Tosaf to provide them with the best UV light stabilizer for this application. CYASORB CYNERGY SOLUTIONS® B877 Stabilizer is exclusively produced by Solvay,” says Sophie Poelmans, Global Marketing Manager for Polymer Additives at Solvay’s Technology Solutions global business unit.

“Tosaf is a leading producer in the world of masterbatch and compounds for stadium seats. We have developed solutions that are tailored to this hard-wearing application, combining protection from weathering, UV, and fire, while meeting the standards and country-specific regulatory requirements. Together with Solvay, we work on the continuous development of high-quality masterbatch products for valuable, durable end applications,” explains Oren Moshe, FR Business Unit Manager of Tosaf.

A high-performing UV absorber for plastics to protect your stadium seat

Stadium seats typically consist of polypropylene (PP). Along with polyethylene (PE), polypropylene is one of the most versatile types of plastic. In fact, polypropylene is found in nearly every market sector that uses plastics. A disadvantage of polypropylene, however, is its high degradation rate when exposed to UV light sources, such as the sun. Light and heat cause the bonds holding the polymer together to break, weakening the plastic. Without the proper UV light stabilization package, your stadium seat would suffer from discoloration and the UV degradation of plastics, becoming brittle and eventually starting to crack after only a few months of outdoor exposure. CYASORB CYNERGY SOLUTIONS® B877 Stabilizer will protect the structure and appearance of your seat, even after several years of outdoor exposure.

UV Light Stabilization Solutions for Stadium Seating

Aside from UV light stabilizers, other additives are added to the polypropylene. Typically, stadium seat formulations also contain pigments for coloration and flame retardants, depending on the geographical location of the project. The components of a stadium seat formulation must be carefully selected to ensure there are no negative interactions. This process requires specific expertise, which Tosaf has mastered exceptionally well. The combination of Tosaf’s flame retardant structure and Solvay’s UV light stabilizer technology has been used successfully in more than 30 different color systems, all of which have been approved in the market and have demonstrated exceptional long-term UV durability and color retention.

So the next time you take a seat to watch an outdoor sports game, for instance in the Amsterdam Arena, rest assured that Solvay and Tosaf have you covered.
