Syensqo and ZF win prestigious SPE Automotive Award 2024

This innovative thermoplastic outboard housing, the first to be used in a steering system over a metal one, won third place in the Chassis Unit – Structural Component category, recognising outstanding advancements of plastics for the technology and design of tomorrow’s vehicles. The combination of Xencor^TM HPPA long-fibre technology with the component’s design, achieves the necessary rigidity and stability to withstand extreme temperatures (-40°C to +125°C) and dynamic loads, all while offering a favorable cost-performance ratio. The use of Xencor^TM HPPA LGF thermoplastic over metal enabled weight saving of approximately 40% in this application.

“Syensqo’s specialty polymers have advanced lightweight, fuel-efficient, and cost-effective mobility solutions for decades. We’re honored to receive this award as a testament to our proficient collaboration with ZF Group and Volvo in a crucial automotive application,” said Georges Houtappel, Executive Vice President of Transportation at Syensqo.

Given the safety-critical nature of the steering system, Syensqo developed comprehensive durability and aging models to ensure long-term reliability. The innovative one-shot injection molding process used for this component allows the integration of functional elements, such as metal dowel pins for precise alignment and molded sealing ribs to enhance sealing performance. Unlike traditional aluminum high-pressure die-casting housings, the thermoplastic material provides inherent corrosion resistance, eliminating the need for additional anodisation.
