Core Insights - Hyundai Transys and BASF have developed a modular concept seat specifically for purpose-built vehicles (PBV), utilizing advanced materials and supercritical fluid (SCF) injection foaming technology [2][3] - The Elastollan® thermoplastic polyurethane (TPU) used in the seat is 100% recyclable, supporting sustainable automotive interior solutions [3] Group 1: Material Innovation - The SCF injection foaming technology allows for uniform gas dispersion, creating a consistent foam structure that enhances mechanical properties, reduces density, and minimizes volatile organic compound (VOC) emissions [2] - This innovation initially applied in the footwear industry is now being adapted for automotive interiors, enabling lightweight, durable, and high-quality components [2] Group 2: Sustainability and Compliance - The foaming process does not use crosslinking agents or chemical blowing agents, making the product easier to recycle after consumer use, thus aligning with the EU's proposed End-of-Life Vehicles Regulation (ELVR) for circular design principles [3] - Reduced energy consumption during production contributes to carbon neutrality and emission reduction goals for companies, providing lower ownership costs for end-users at the vehicle end-of-life stage [3]
