BASF and Hyundai Transys Collaborate to Develop Modular Concept Seat Using Recyclable TPU

Hyundai Transys and BASF have collaborated on a modular concept seat for purpose-built vehicles (PBV), demonstrating how the advanced material solution of Elastollan® thermoplastic polyurethane (TPU), processed with Supercritical Fluid (SCF) injection foaming technology, can facilitate customizable and sustainable seating solutions for automotive interiors. The modular concept seat incorporates a headrest and armrest constructed with advanced material solutions for the first time.

“Our collaboration with Hyundai Transys exemplifies how material innovation and design thinking can converge to shape the future of mobility,” said Andy Postlethwaite, Senior Vice President, Performance Materials Asia Pacific. “Elastollan TPU is 100% recyclable, and when combined with SCF injection foaming technology, it offers a smart and sustainable solution for automotive interiors.”

First introduced to the footwear industry, this material innovation is now being applied to automotive interiors. It allows tier suppliers and OEMs to create lightweight, abrasion-resistant components with a soft-touch feel and premium look. This is attributable to the SCF injection foaming technology, which evenly disperses gas to produce a uniform fine-cell structured foam – resulting in improved mechanical performance, lower density, and lower volatile organic compound (VOC) emissions.  

Additionally, no crosslinking or chemical blowing agents are used in the foaming process, enabling post-consumer recyclability with easy disassembly and reuse. This supports automotive companies’ compliance with the EU’s proposed End-of-Life Vehicle Regulation (ELVR), which emphasizes circular design principles. As less energy is required during production, overall energy consumption is reduced, which helps companies to meet carbon neutrality and emission reduction goals. End users may also enjoy cost-to-own (CTO) benefits at the point of disposal.
