An impact absorber made of the polyamide particle foam Ultramid® Expand jointly developed by BASF and Mercedes-Benz for the Mercedes-Benz VISION EQXX technology program has won 2nd place in the "Enabler Technology" category at the SPE Automotive Awards 2024. SPE stands for Society of Plastics Engineers (Internationale Gesellschaft für Kunststofftechnik e.V.), which honors outstanding developments in plastic parts for vehicle engineering every year.
The purpose of an impact absorber is to absorb and distribute the forces arising in a crash and transfer them to the vehicle body. Metal structures, complex and expensive to process, are often used for this. Ultramid® Expand offers several advantages here: Using the polyamide particle foam reduces weight and improves energy absorption in the event of an impact. The production process is also more cost-effective than for metal structures.
Ultramid® Expand is ideal for use in the automotive sector. Ultramid® Expand is a particle foam that withstands the body-in-white painting process, can be used as a reinforcing insert in later closed structures of the car body and can be installed in the body-in-white due to its high temperature resistance. The particle foam fulfils the demanding requirements of the automotive industry for the interior and for long-term use.
Ultramid® Expand particle foam is based on a combination of several polyamide (PA) 6 types. It consists of pre-expanded particles with a defined particle size and density, which can be welded into a 3D component in a molding machine without producing foam waste. The particle foam can be easily processed on existing steam chest molding machines.
Another benefit is that the polyamide particle foam lends itself excellently to overmolding with materials of the same material. “This enables completely new types of hybrid components that can be recycled as single-material thermoplastic systems at the end of their life cycles,” René Holschuh, Segment Manager Transportation at BASF Performance Materials Europe, stresses. “Ultramid® Expand can therefore help to close the materials cycle – without compromising the mechanical properties of the components during their service life.”

BASF and its customer Evonik have agreed on the first delivery of BASF’s ammonia BMBcertTM grade. Thereby, both chemical companies demonstrate their commitment to offer products with a reduced product carbon footprint (PCF). With its ammonia BMBcert, BASF delivers to Evonik a product whose PCF is at least 65 % lower than the standard product*. Both, BASF and Evonik are extending their product portfolios and launching ammonia-based products applying a biomass balance approach. These products are readily available via existing sales channels and fully integrated into the ERP (Enterprise Resource Planning) systems of the companies.“Evonik and BASF share the same vision: We are convinced that the chemical industry can transform and replace fossil with renewable feedstocks and utilities. The supply with ammonia BMBcert is a big milestone for both of us,” said Dr. Jens Aßmann, Vice President Business Management Ammonia Value Chain and Operations Amino Resins at BASF. Evonik has received a first shipment of ammonia BMBcert produced by BASF. By incorporating BASF’s ammonia BMBcert into its ISCC (International Sustainability and Carbon Certification) PLUS certified production processes, Evonik demonstrates its commitment to a more sustainable economy and its ambitious emissions reduction targets. By 2030, Evonik seeks to reduce Scope 1 and 2 emissions by 25 % and Scope 3 emissions by 11 % compared to 2021 levels, and to become climate-neutral by 2050, in line with the Paris Agreement and validated by Science Based Target Initiative (SBTi). Evonik plans to use ammonia BMBcert to produce a range of sustainable products, including VESTAMIN® IPD eCO and VESTAMID® eCO Polyamide 12. “eCO” stands for Evonik’s aim to eliminate CO2 via mass balance approach using renewable feedstock in existing systems and production processes. With the eCO grades, customers benefit from more sustainable products with no compromise in performance. Thus, conventional, trusted VESTAMIN curing agents for epoxy resin systems with typical applications in industrial flooring, marine and anticorrosive paints can easily be replaced by the IPD eCO grade. The same proves true for VESTAMID eCO Polyamide 12, which covers tailored, high-performance polyamide, typically found in shoe soles, sunglasses, gas pipes, safety-related automotive parts and many more. “We are excited to partner with BASF to source ammonia with a reduced carbon footprint. This collaboration witnesses our dedication to environmental stewardship and our ability to innovate in a rapidly changing market,” said Silvia Torrado, Global Procurement Director for Base Petrochemicals at Evonik.BASF applies a biomass balance approach to replace fossil resources at the beginning of the production process with certified biomethane from biowaste raw materials which are attributed to the product. The mass-balanced product is certified according to ISCC PLUS standards. In addition, BASF is using electricity from renewable sources for the manufacturing of the ammonia, further reducing its PCF. As outlined in its sustainability roadmap, the BASF Monomers Division announced to offer at least one circular or lower PCF option for every major product line by 2025. Mass balanced products are drop-in solutions, meaning they have the same properties as the corresponding conventional products, but with an attributed share of circular raw materials. The division’s sustainable offerings are an essential part of BASF’s path to climate neutrality and net-zero CO2emissions by 2050. * Based on the average CO2 footprints stated in the “Default values for the transitional period for the CBAM between October 1, 2023 and December 31, 2025” published by the European Commission on Dec 22, 2023.
