Syensqo & Vertical Aerospace Partner to Advance VX4 Aircraft Industrialization

Syensqo, a global leader in advanced materials, and Vertical Aerospace, a global aerospace and technology company that is pioneering electric aviation announced a new long-term supplier partnership.

Syensqo’s high-performance composite and adhesive materials, already used in Vertical’s prototype program, have been selected for the VX4 aircraft, which is targeting certification in 2028 before entering commercial service. This comes after multiple years of close collaboration between the teams at Syensqo and Vertical.

Syensqo’s advanced materials will be integrated across the entire structure, providing the lightweight strength, structural efficiency and durability required for the high-cycle operations of electric vertical flight. Securing advanced composite materials is critical in ensuring the VX4 can withstand repeated take-offs and landings while maintaining safety and performance at scale.

The VX4’s airframe itself will be manufactured by Aciturri, a leading global aerostructures supplier, supporting Vertical’s transition into full commercial production.

Syensqo brings extensive aerospace experience, supplying advanced materials to many of the world’s leading aircraft manufacturers and defense companies. This experience makes Syensqo an ideal partner as Vertical advances toward both civil and defense applications of its aircraft platform.

Rodrigo Elizondo, President of Syensqo Composite Materials, expressed confidence in the strengthened partnership with Vertical, stating that Syensqo’s advanced composite and adhesive technologies are engineered to drive new levels of lightweighting and performance for the VX4. He added that as Vertical moves toward certification and industrial-scale production, Syensqo looks forward to contributing its scientific expertise and deep customer collaboration to support the VX4’s successful transition into full-scale manufacturing.

Stuart Simpson, CEO of Vertical Aerospace, emphasized the importance of the company’s partnership ecosystem, stating that bringing the VX4 to market alongside leading global partners is central to their mission. He noted that strengthening their long-standing collaboration with Syensqo as the advanced-materials supplier marks a critical step forward. With Syensqo’s decades of expertise in lightweight, high-performance composites and a shared commitment to safety and certification, Simpson affirmed that this partnership will play a key role in delivering a resilient, agile aircraft as Vertical advances toward commercial operations.
