Dextra and Arkema Forge Partnership to Revolutionize Composite Solutions

Arkema, a titan in specialty materials with a robust focus on sustainable innovations, has joined forces with Dextra Group, a pioneer in the construction industry known for its cutting-edge Glass Fiber Reinforced Polymer (GFRP) solutions, to unleash groundbreaking composite fiber solutions. This collaboration is set to redefine industry standards, leveraging Arkema’s acclaimed Elium thermoplastic resin and Dextra’s innovative FRP rebar to deliver unique, high-performance materials focused on sustainability and efficiency in construction.

The partnership marks a visionary step towards the future of construction materials, positioning both Arkema and Dextra Group at the forefront of technological acceleration in the composites sector. Through this initiative, they aim to drive the adoption of composite material in construction, emphasizing innovative solutions, sustainability, and the superior qualities of Glass Fiber Reinforced Polymer, thus setting a new benchmark for quality and innovation in the industry.

Dextra’s innovative FRP rebar, combined with Arkema’s Elium® resin, presented at JEC World 2024, encapsulates the essence of this partnership, highlighting Dextra’s leadership in GFRP innovation for the construction industry.

Overview of Arkema and Dextra Group’s Collaboration

In a groundbreaking collaboration, Arkema, a global leader in specialty chemicals, has joined forces with Dextra Group, a trailblazer in the construction industry. This partnership is set to revolutionize the construction sector with the introduction of innovative composite solutions. Below are the key aspects of this collaboration:

  • Arkema’s Contribution:
    • Leveraging its expertise in specialty materials, Arkema brings to the table its pioneering Elium® thermoplastic resin, known for its exceptional performance in enhancing the strength and durability of composites.
  • Dextra Group’s Role:
    • Operating in over 55 countries, Dextra Group’s expertise in engineered steel and fibre-reinforced polymer construction products sets a solid foundation for this collaboration. The focus on sustainability is evident through Dextra’s introduction of Environmental Product Declarations (EPDs) for their products, showcasing a shared vision for a greener future.

This collaboration not only underscores the commitment of both organizations to pioneering sustainable, high-performance materials but also sets Dextra apart as a leader in GFRP innovation within the construction sector.

Arkema’s Elium Thermoplastic Resin and Dextra’s FRP Rebars

At the heart of the collaboration between Arkema and Dextra Group lies the integration of Arkema’s Elium® thermoplastic resin with Dextra’s innovative FRP rebars, setting a new standard in the construction industry for composite fiber solutions. This partnership leverages the unique properties of Elium® resin, including:

  • Hot Bending on Site: Elium® resin allows for the hot bending of FRP rebars directly on construction sites, offering unparalleled flexibility and cost-efficiency. This feature is a game-changer, simplifying logistics and enabling more complex architectural designs.
  • Sustainable and High Performance: This new generation of resin can be made with up to 92% recycled material. At the end of the products lifetime (120+ Years), it can be broken down to separate the resin and fiber elements. This allows the resin to be recycled and reused while the fiber can be upcycled to be used as reinforcement in asphalt and concrete.

Arkema’s collaboration with Dextra to develop bendable reinforcements using Elium® resin further underscores the innovative spirit of this partnership. This endeavor not only makes reinforcements more flexible but also enhances their resistance properties, longevity, and aesthetic appeal, mirroring natural stone.

Through this collaboration, Dextra Group is positioned as a leader in GFRP innovation, differentiating itself from other producers by harnessing the unique benefits of Arkema’s Elium® resin and its unique manufacturing process.

 

Tai Po Railway Pier – Reconstruction of Tai Po Kau Tide Gauge Station

 

Tai Po Railway Pier – Reconstruction of Tai Po Kau Tide Gauge Station, Hong Kong

 

Dans le paysage côtier dynamique de Tai Po Kau, dans les Nouveaux Territoires de Hong Kong, les projets d'infrastructure exigent des solutions robustes et résilientes. L'un de ces projets, le projet de reconstruction de la station marégraphique de Tai Po Kau, nécessitait des matériaux innovants pour résister aux défis uniques posés par son environnement. Dextra est intervenu pour fournir environ 1 000 mètres de Glass Fibre Reinforced Polymer (GFRP) rebar for the slab of the Tai Po Railway Pier, démontrant l'efficacité des matériaux composites avancés dans la construction marine.

Le projet de station marégraphique Tai Po Kau visait à revitaliser l'infrastructure existante, en renforçant sa résilience contre les forces de marée, la corrosion et la dégradation de l'environnement. Conscient des limites du renforcement traditionnel en acier dans les environnements marins, le projet a recherché des alternatives susceptibles d'offrir une durabilité et une longévité supérieures. Dextra Barres d'armature en PRV est apparu comme la solution idéale, offrant une résistance exceptionnelle à la corrosion, à la rouille et à la dégradation chimique généralement associée à l'exposition à l'eau salée.

Barres d'armature en PRV, composé de fibres de verre à haute résistance incorporées dans une matrice polymère, offre des propriétés mécaniques comparables à celles de l'acier mais avec des avantages supplémentaires. Notamment, Barres d'armature en PRV présente une conductivité thermique nettement inférieure, réduisant le risque de ponts thermiques et améliorant l'intégrité structurelle dans des variations extrêmes de température. De plus, ses propriétés non magnétiques éliminent les interférences électromagnétiques, ce qui le rend adapté aux applications sensibles telles que les stations marégraphiques.

L'application de Barres d'armature en PRV within the Tai Po Kau Tide Gauge Station project encompassed both straight and bend bars, catering to the diverse structural requirements of the public pier. Dextra’s expertise in custom fabrication ensured precise bending and shaping of the rebar to fit the intricate geometries of the pier structure, facilitating seamless integration and minimizing construction complexities.
