• ELIUM® liquid thermoplastic resins
• A new supply chain model
• Recycling solutions

Arkema develops new solution to manufacture composite reinforcement bars (rebars) for concrete using the liquid thermoplastic resin ELIUM® in place of conventional thermosetting solutions.
Composite rebars do not rust or corrode, are relatively insensitive to snow-clearance salts and chemicals used for de-icing, and have an interesting weight to strength ratio. These properties already make them an economically viable and more effective alternative to epoxy-coated steel rebars when life cycle cost is considered. The implications are significant for coastal or cold areas.
Based on the reactive liquid thermoplastic resin technology ELIUM®, a new generation of rebar has been developed that combines the qualities of composites with the new possibilities offered by the use of a thermoplastic matrix. Unlike most thermoplastic resins, ELIUM® can be easily processed through traditional pultrusion using exclusively standard equipment.
ELIUM® -based rebars and cables can be re-heated and easily shaped or bent, reducing the cost of supplying rebars with custom shapes. Moreover, the use of thermoplastic matrix open a way for GFRP recycling of spare part, with a potential strong reduction in environmental impact.
Different solutions are considered to find the most relevant way to recycle rebar wastes. Of course, the mechanical recycling is already well known for thermoplastic materials. Acrylic matrix offer a good miscibility in a wide range of virgin polymers.
Then, the chemical recycling process consists of the polymerization of the matrix to collect the monomers that compose it. After distillation, the purity of the monomers is higher than 99% and comparable with the same monomers from the conventional petrochemical path.
