Motoring onwards: automotive materials


Recent developments in new automotive materials include a TPE with 50% recyclate, a project to develop bio-based carbon fibres and superior grades of PA, PBT and PP


The automotive sector is a key proving ground for injection moulding, and new materials – from high-temperature resins to carbon fibre and additives – play a critical role. Syensqo recently launched Cyasorb Cyxtra V9800 and V9100, a new stabiliser series that helps automotive manufacturers and compounders expand the use of translucent polypropylene (PP) for both interior and exterior applications Translucent PP can offer creative possibilities to automotive designers but its sensitivity to UV and heat has historically limited its use in demanding environments. The two new stabilisers address this, helping


materials maintain clarity, colour and performance over time. The V9800 grade is optimised for exterior


applications like bumpers – which require higher UV stabilisation – while V9100 is engineered for interior

applications that need higher thermal stabilisation. One key benefit is control of discoloration and yellowing – as the series delivers minimal yellowing under light and heat exposure and provides a minimal contribution to the yellowness index. In addition, it retains light transmittance and gloss properties – preventing blooming under light and heat exposure. It also protects mechanical proper- ties and aesthetics, leading to visually appealing products that retain quality throughout their lifecycle. “As automotive design continues to evolve,


material performance must keep pace,” said Chen Ning, vice president of polymer additives at Syensqo. Separately, the company introduced a portfolio


of busbar solutions at K2025. For extruded bus- bars, used in battery systems, it has developed Ryton PPS XE3500 Orange grade, for higher
