Converting the frunk (front trunk) for Ford’s electric F-150 from SMC to a Celanese LFT cut weight by 7.25kg and delivered annual cost savings of $15m
interior space. In this part, a PP LFT again replaced SMC to reduce weight and improve recyclability. “Tight packaging space and the requirement of

This console carrier for GM is produced in a Celstran PP LFT from Celanese, offering better functionality and weight savings over its thermoset predecessor
an HVAC outlet in the console posed a challenge, as a traditional through-pin-type hinge could not be used on the armrest to keep it latched during a crash,” says Helms. “A friction hinge with an inertial lock, previously used in the furniture industry, was used to overcome this issue. This approach required unique tooling innovation to be feasible, resulting in the development of the first triple- action, two-stage slide featuring a horn-pin driven slide with collapsible lifters on top of a hydraulic main bottom slide. This innovation enabled direct edge gating and optimised filling conditions. This resulted in an optimised carrier part design with additional structure, passing all abuse load testing at 900N load.” Across the EV space, thermal properties and

structural analysis, and more,” says David Eastep, Senior Manager Product, Technology and Innova- tion, Engineered Materials, at Celanese. He says that formulation selection and processing were key to achieving the required part performance and surface appearance. Celstran PP was also used in another part in the SPE innovation competition — a novel console structural carrier from GM for a latchless armest with friction hinge and inertia lock that frees up
flame retardancy are particularly important. “Several unique flame test standards are being developed, outside the standard UL94 V0, for the EV and [internal combustion engine] automotive applica- tion space to meet the challenging flame-retardant requirements of OEMs for automotive components such as EV battery enclosures, battery systems, housings, covers, and more,” says Eastep. “[For] electronic housings that resist thermal warping and industrial components that must maintain their shape under thermal stress, the long fibres in polyamide-based LFRTs offer an elegant solution.” New material solutions for EV battery enclosures
are key for advancing EV technology, according to SABIC. The company provided a 30% long-glass fibre (LGF) PP with an intumescent, halogen-free
