BASF and LEMON Co., Ltd. (LEMON) have signed a Memorandum of Understanding (MoU) to jointly develop new material solutions using Freeflex®, a fiber made from BASF’s Elastollan® thermoplastic polyurethane (TPU) on October 16. LEMON, a leading producer of functional nanomembranes, will incorporate Freeflex into the production of its waterproof and windproof apparel. The agreement also outlines future opportunities for collaboration in technology development and business expansion.

“This partnership with BASF allows us to expand the application of our electrospinning technology and deliver high-performance nanofiber materials to global brands,” said Lee Jong-il, Chief Executive Officer, LEMON. “By combining our expertise in nanomembrane development with BASF’s material innovation, we aim to set new standards in functional textiles.”

Freeflex is a high-performance BASF material engineered for fabricating nanomembranes with a reticular structure via electrospinning.  This material offers high water repellency, improved air permeability, and is ultralightweight. It is designed to perform reliably under extreme environmental conditions while maintaining comfort and durability.

“Freeflex demonstrates how material science can contribute to the future of high performance and more sustainable clothing,” said Rohit Ghosh, Vice President, Business Management TPU, Performance Materials Asia Pacific, BASF. “We are excited to introduce advanced TPU fiber technology to the South Korea’s apparel industry through the partnership with LEMON.”

In addition to its functional benefits, Freeflex is made without the intentional use of Per- and polyfluoroalkyl substances (PFAS) and is fully recyclable. These attributes align with both companies’ commitment to more sustainable innovation.
