BASF and LEMON to develop solutions for functional apparel
BASF and 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).

BASF and LEMON sign Memorandum of Understanding to co-develop new material solutions for apparel.
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. By combining our expertise in nanomembrane development with BASF’s material innovation, we aim to set new standards in functional textiles,” said Lee Jong-il, Chief Executive Officer, LEMON.
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 ultra-lightweight. It is designed to perform reliably under extreme environmental conditions while maintaining comfort and durability.
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.
“Freeflex demonstrates how material science can contribute to the future of high performance and more sustainable clothing. We are excited to introduce advanced TPU fiber technology to the South Korea’s apparel industry through the partnership with LEMON,” said Rohit Ghosh, Vice President, Business Management TPU, Performance Materials Asia Pacific, BASF.
