SABIC’s thermoplastic materials for EV battery sustainability, efficiency, and safety

September 21, 2022


SABIC’s thermoplastic materials are well-suited for electric vehicle (EV) and supply equipment (EVSE) battery applications. SABIC’s Petrochemicals and Specialties businesses are highlighting their latest material solutions to address battery requirements, including sustainability, efficiency, safety, and reliability. SABIC’s new strategic BLUEHERO initiative expands the ecosystem of materials, solutions, and expertise designed to help accelerate the shift to electric power.

“Electric vehicle manufacturers are focusing on higher efficiency to improve range and performance, which are top consumer issues,” said Abdullah Al-Otaibi, general manager, ETP & Market Solutions, SABIC’s Petrochemicals business. “In addition to exploring higher-voltage batteries, their strategies include replacing traditional battery materials, like metals, with thermoplastics. By reducing weight and expanding design freedom, SABIC’s solutions can help enable long-term efficiency gains. We’re making further advancements through our new BLUEHERO ecosystem, which applies systems engineering principles to help customers enhance EV battery design and manufacturing with thermoplastics.”

“The global transition to electrification demands continuous innovation in battery materials to realize the full sustainability potential of EVs,” said Maureen MacDonald-Stein, director, Growth OEMs, and Markets, SABIC’s Specialties business. “We combine a broad and diverse portfolio of thermoplastic resins, compounds and copolymers with design, application development and regulatory expertise. These global resources are helping customers reimagine battery design, manufacturing, and operation to further enhance environmental benefits and promote circularity. Our high-performance materials can help remove barriers to EV adoption and expand the benefits of clean energy.”

SABIC’s petrochemicals business highlights expanding solutions for EV battery needs
Under BLUEHERO, led by the Petrochemicals business, SABIC has been expanding its portfolio of thermoplastic polymers and its EV expertise to better assist the value chain in addressing challenges, especially the critical safety requirements of batteries exposed to external fires and thermal runaway situations. The business added several flame retardant (FR) materials to its offering, backed by data demonstrating their potential to withstand high temperatures and pressure loads.

The business is presenting results from rigorous thermal runaway testing based on the new UL 2596 standard for battery enclosure materials. The testing revealed STAMAX FR long glass fiber-reinforced polypropylene resin can meet the new UL standard, having passed the test six times in succession without any perforation.

SABIC’s specialties business features proven materials portfolio
To help EV manufacturers address the demands of higher-voltage batteries, SABIC’s Specialties business features NORYL NHP8000VT3 resin. This high-performance, polyphenylene ether (PPE)-based resin achieves the highest comparative tracking index performance level category (CTI PLC0), provides ultra-thin-wall extrusion and thermoforming capability, and meets the UL94 V0 standard at 0.25mm with non-brominated, non-chlorinated flame retardance. It’s well suited for insulation film used in EV battery modules to help protect against short circuits and fire propagation. The insulation film and a thermoformed part made of NORYL NHP8000VT3 resin are on display at SABIC’s booth.

To provide low-temperature ductility performance for robust energy absorption in extremely cold climates, the Specialties business has developed a new NORYL GTX grade. It’s in a battery side impact rocker protection component offering high energy absorption and up to 40% less weight than metal. This new product, which is in the final stages of commercialization, provides superior property retention over a broad range of temperatures from -40°C to 80°C to address battery requirements such as impact strength and stiffness.

The new NORYL GTX grade can sustain e-coat bake temperatures (≤ 200°C for up to 30 minutes) in the automotive assembly process, helping to build multi-material solutions such as metal / plastic hybrids for light-weighting and system cost reduction.
