Shanghai, China – March 11, 2026 – At CHINAPLAS 2026, BASF will showcase an outdoor jacket developed in collaboration with Niber Technologies, incorporating the newly developed FreeflexE 130, a thermoplastic polyurethane (TPU) based electrospun nano membrane. 

The collaboration combines BASF's Freeflex TPU technology with Niber's electrospinning expertise to create an ultralight, soft-touch outdoor jacket offering excellent membrane uniformity and high moisture vapor transmission rate. Made without the intentional use of PFAS, the TPU-based membrane serves as a sustainable alternative to traditional ePTFE materials.

FreeflexE 130 forms 100-600 nanometer ultrafine fibers through electrospinning, creating a high surface-to-volume ratio and highly porous morphology. Alongside this innovation, BASF will also showcase PP/PET sports apparel containing 15% Freeflex melt spun TPU fibers, delivering quick drying performance, elasticity, and durability.

The Freeflex portfolio is advancing through Bluesign certification, expected by 2026, meeting growing regulatory and sustainability requirements of the global apparel and textile industries.
