Syensqo Partners with Vertical Aerospace to Provide Adhesives for VX4 Aircraft

Vertical's full-scale VX4 prototype during piloted flight testing.
Vertical Aerospace, a global aerospace and technology company that is pioneering electric aviation, and Syensqo recently announced a new long-term supplier partnership. According to the new agreement, Syensqo’s high-performance composite and adhesive materials — already used in Vertical’s prototype program — have been selected for the VX4 aircraft. The aircraft is targeting certification in 2028 before entering into 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 takeoffs 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.
Stuart Simpson, CEO of Vertical Aerospace, commented, “We are bringing the VX4 to market alongside leading global partners, and deepening our successful partnership with Syensqo as our advanced-materials supplier is a vital step in that journey. Their decades of expertise in lightweight, high-performance composites — combined with our shared commitment to safety and certification — will help us deliver a resilient, agile aircraft as we progress toward commercial operations.”
Rodrigo Elizondo, president of Syensqo Composite Materials, explained, “We are honored to deepen our collaboration with Vertical. Our advanced composite and adhesive technologies are designed to push the boundaries of lightweighting and performance, supporting the VX4’s journey toward safer, cleaner and more efficient air mobility. As Vertical moves into certification and industrialization, we look forward to bringing our scientific expertise and strong customer partnership to support the VX4’s successful entry into full-scale production."
This extension of Vertical’s partnership with Syensqo comes as Vertical continues to formalize the core supply chain for its certification aircraft, alongside Honeywell, Aciturri, and other global partners.
