BASF and Lemon sign MoU to co-develop TPU-based apparel materials

BASF has signed a memorandum of understanding (MoU) with South Korea’s Lemon to co-develop new material solutions for performance apparel using Freeflex, a fiber made from BASF’s Elastollan thermoplastic polyurethane (TPU). The agreement, announced on October 16, outlines collaboration on product development and future business opportunities in functional textiles.

Lemon, a producer of functional nanomembranes – whose name is an acronym of Leading Emi and Membrane Of Nanotechnology – plans to incorporate Freeflex into waterproof and windproof garments. The partners say the TPU-based fiber enables electrospun nanomembranes with a reticular microstructure that combine high water repellency with improved air permeability and low weight – attributes sought by outdoor and sportswear brands seeking comfort alongside protection. 

According to BASF, the material is manufactured without the use of PFAS and is fully recyclable, aligning with brand and regulatory pressure to reduce persistent chemicals and improve circularity in textile supply chains. The collaboration is expected to pair Lemon’s electrospinning expertise with BASF’s polymer development to accelerate commercialization of next-generation breathable barriers and laminates. 

Lemon’s chief executive Lee Jong-il said: "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."

Rohit Ghosh, vice president for TPU in BASF’s Performance Materials Asia Pacific business, said: "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."

The announcement follows a series of TPU-related moves from BASF in Asia this year, including showcasing Elastollan grades for food-contact conveyor belts and medical tubing at Chinaplas 2025, and broader initiatives to localize TPU capabilities closer to regional customers. Together, the BASF–Lemon MoU signals continued momentum behind TPU in technical apparel as brands seek PFAS-free water resistance, durability, and recyclability without sacrificing wearer comfort.
