Lemon Co., Ltd. is a South Korea-based advanced materials manufacturer specializing in the development and mass production of high-performance functional nanofibers and nanomembranes utilizing proprietary electrospinning technology. Founded in 2012 and headquartered in Gumi-si, South Korea, the company operates as a subsidiary of TOPTEC Co., Ltd. and serves clients across domestic and international markets. Lemon organizes its business operations into three primary divisions: Nanomembrane, Health and Beauty (H&B), and Electronics Materials. The company's core product portfolio encompasses functional outdoor and industrial membranes marketed under the NEXTURE brand for breathable, waterproof, and windproof technical textiles; personal hygiene and healthcare goods marketed under the Air Queen brand, including nanofiber sanitary napkins, respiratory masks, breast pads, and protective garments; electronic components such as electromagnetic interference (EMI) shielding films, heat dissipation sheets, conductive tapes, and 5G printed circuit board (PCB) materials; industrial ventilation filters and agricultural protective bags; and advanced energy solutions, including ultra-thin, high-strength, heat-resistant electrolyte supports and separators for solid-state and secondary batteries. In recent strategic developments, Lemon has expanded its focus on sustainable materials to comply with tightening international environmental regulations concerning per- and polyfluoroalkyl substances (PFAS). Notably, the company formed a strategic collaboration with BASF to co-develop recyclable, PFAS-free, waterproof apparel membranes combining Lemon's nanofiber web technology with BASF's Freeflex thermoplastic polyurethane (TPU) materials. Additionally, Lemon has advanced the commercialization of its solid-state battery electrolyte support materials and executed targeted capital increases through third-party share allotments to finance next-generation manufacturing capacity and strengthen working capital.
