The bio-based plastic in question is Elastollan® N, the thermoplastic polyurethane from BASF. It is a corn-based biopolymer. Depending on the type of TPU, the proportion of renewable raw material is 45 to 60 percent. The highlight, the TPU offers the same durability, flexibility and mechanical properties as well as the hydrolysis, chemical and UV resistance as conventional Elastollan®. Even the processability parameters are retained. A special feature is that the proportion of biomaterial in the finished product can actually not only be detected, but precisely measured (according to ASTM D 6866).
"BASF's bio-based TPU is a true high performer and is in no way inferior to conventional fossil fuel. A quick changeover in production is possible and the right step to bring our customer real added value through a more sustainable product," explains Oliver Mühren, Group Manager Sales at BASF Polyurethanes GmbH.
Looking at the life cycle assessment, the bio-based product achieves an improvement in CO2 footprint of approximately 15 percent. And so, it is the logical consequence that the Elastollan® N is part of BASF's circular economy strategy and contributes to saving fossil resources and CO2 emissions. LAPP is also aiming, step by step, to further expand its portfolio of bio-based sheath materials.
