Nanomembrane in development at BASF & Lemon

20/10/2025
BASF’s Freeflex, a fibre made from a thermoplastic polyurethane (TPU), will be used in an electrospun film by Korean company Lemon. The two companies have signed a memorandum of understanding to jointly develop the functional nanomembrane.  

BASF’s Elastollan-branded TPU has been used to make microporous waterproof-breathable membranes since its launch. The polymer will now be used to make a non-woven film via electrospinning. These types of membranes are said to offer high water vapour permeability. They are also made without the intentional use of PFAS chemistry, said BASF. 

“By combining our expertise in nanomembrane development with BASF’s material innovation, we aim to set new standards in functional textiles,” said Lemon CEO Lee Jong-il.

Lemon specialises in nanofunctional materials using proprietary nanofiber spinning and composite material design processes. It has recently expanded its business to develop components for electronics offering electromagnetic shielding or heat dissipation.
