Solvay’s Xencor LFT compounds enable Stajvelo to make the world’s first e-bike out of advanced injection-moulded composite materials. The innovative urban e-bike combines mobility, comfort and design and Solvay will have the e-bike on display at K 2019 in Hall 6 Booth C61.

Monaco-based Stajvelo selected Solvay’s long-fibre Xencor polyarylamide (PARA) compound based on its ability to meet stringent structural, mechanical, and aesthetic requirements. Xencor PARA significantly extends the performance capabilities of Solvay’s Ixef PARA compounds, which have successfully replaced metal in medical devices, automotive exteriors, and small appliances where a highly aesthetic surface finish is required. 

“Stajvelo’s e-bike design embodies the hard-to-achieve balance between form and function, due in part to Xencor PARA’s unique combination of properties,” said Thierry Manni, Founder and CEO of Stajvelo. “Thanks to Solvay’s polymer expertise and processing technology support, we were able to design a manufacturing process with optimal function integration and time-saving assembly operations.”

Solvay’s Xencor LFT compounds typically contain between 30 to 60 percent fibre reinforcement, depending on the polymer and grade. The fibre constitutes a critical structural element by creating an entangled 3D fibre skeleton within the final molded part. The strong fibre skeleton provides vastly superior structural properties and dimensional stability compared to traditional highly-filled, short-fibre reinforced polymers.

Xencor LFT compounds are intended to bridge the price-to-performance gap between short fibre thermoplastics (SFT) and advanced composite materials. They combine high strength, outstanding crash/impact performance, thermal stability, very low creep, excellent surface aesthetics, and smooth processing characteristics.

“Xencor compounds are designed to replace metal in semi-structural applications that require greater performance than is attainable with SFT products and where metal is not a desirable option due to weight or per-part cost,” said Eric Martin, Global Manager for Xencor LFT compounds for Solvay’s Specialty Polymers global business unit.

Solvay’s Xencor LFT compounds are suitable for semi-structural applications in a variety of markets including automotive, advanced transportation, construction, industrial, and consumer, as well as sports and leisure.
