Advanced polymers for automotive performance and circularity

SABIC presented a portfolio of specialty thermoplastics at PIAE 2026 in Baden-Baden, Germany (March 18–19, 2026), targeting automotive applications such as exterior components, ADAS systems, lighting modules, and EV battery structures. The materials focus on enabling circular material use, improved thermal management, and enhanced design flexibility within the automotive data ecosystem.

Recycled-content materials for exterior durability
A key development is the introduction of LNP ELCRIN SLX2373RCC and SLX2375RCC compounds, incorporating 30% and 45% post-consumer recycled (PCR) content, respectively. These materials are engineered for high-gloss exterior parts with molded-in color, eliminating the need for painting processes that typically generate volatile organic compound (VOC) emissions.

The compounds provide resistance to weathering and mechanical impact, supporting longer service life in exposed automotive components such as shark fin antennas and ADAS radomes. By integrating recycled feedstock and enabling paint-free processing, the materials contribute to reduced lifecycle emissions and improved recyclability at end-of-life.

Thermal management in ADAS electronics
For advanced driver assistance systems (ADAS), SABIC introduced a thermally conductive compound designed to address heat dissipation challenges in compact electronic assemblies. The material enables replacement of die-cast aluminum in radar and electronic control unit (ECU) housings.

This substitution reduces component weight while maintaining required thermal conductivity, contributing to system-level efficiency. Compatibility with manufacturing processes such as laser welding and heat staking allows integration into existing automotive production lines without major process changes.

In parallel, the EXTEM RH1017UCL resin supports optical applications by withstanding lead-free reflow soldering temperatures. This capability is relevant for optical sensor lenses used in driver monitoring systems and gesture recognition, as well as high-speed optical connectivity in next-generation vehicle architectures.

High-temperature materials for automotive lighting
Thermoplastics designed for automotive lighting applications address increasing thermal and optical requirements in systems such as digital matrix LED headlights. Materials capable of withstanding temperatures up to 230°C are used in components including reflectors, brackets, and lens assemblies.

These polymers reduce component weight and minimize outgassing, which is critical for maintaining optical clarity and long-term performance. Additionally, they enable direct metallization processes, simplifying manufacturing steps in complex lighting modules.

Structural applications in electric vehicles
In electric vehicle (EV) architectures, thermoplastics are increasingly evaluated as alternatives to metals and traditional engineering plastics. A honeycomb energy absorber concept for battery protection demonstrates this transition.

The injection-molded structure is designed for installation within the rocker panel, where it provides side-impact energy absorption across a wide temperature range. Compared to polyamide, the material offers improved ductility at low temperatures and higher stiffness at elevated temperatures, enabling consistent performance under varying operating conditions.

The use of thermoplastics also facilitates complex geometries and part consolidation, reducing assembly steps and supporting lightweighting strategies critical for EV efficiency.

Integration within the automotive data ecosystem
The presented materials align with broader industry requirements for integrating electronics, sensors, and lightweight structures within a connected automotive data ecosystem. By addressing thermal management, electromagnetic compatibility, optical performance, and recyclability, these polymers support the convergence of mechanical and electronic system design.

SABIC’s portfolio reflects ongoing material development aimed at balancing performance, manufacturability, and circularity in next-generation vehicles, particularly as OEMs and suppliers adapt to electrification and increasing ADAS complexity.
