BASF and South Korea’s Lemon have signed a memorandum of understanding (MoU) to integrate Freeflex, a thermoplastic polyurethane (TPU) fibre made from BASF’s Elastollan, into Lemon’s production of waterproof and windproof apparel. The partnership also aims to pursue joint technology development and business expansion in high-performance textile applications.
Developed through electrospinning, Freeflex forms reticular nanomembranes that offer exceptional water repellency, air permeability, and durability. The ultralight TPU material is PFAS-free, fully recyclable, and engineered to maintain comfort and flexibility under extreme conditions—making it well suited for outdoor and activewear.
Lemon CEO Lee Jong-il said the partnership “expands the application of our electrospinning technology and delivers high-performance nanofiber materials to global brands,” while Rohit Ghosh, BASF’s vice president for performance materials Asia Pacific, highlighted Freeflex as “a step toward more sustainable, high-performance clothing.”
Beyond apparel, BASF notes that Freeflex enhances drape, shape retention, and comfort in products ranging from footwear and hosiery to home textiles and furniture. The collaboration underscores a broader industry shift toward PFAS-free materials and recyclable performance fabrics, reinforcing how material science is driving the next generation of sustainable functional textiles.
