BASF’s latest footwear concepts include circular options
13/09/2023
Among the developments is a process that uses granulated PU waste from sole production to produce new soles. BASF has developed PU foams with thermoplastic properties that can be processed with TPU in the injection molding process. This creates TPU soles or other components on the shoe with a recycled content of up to 30%.
Felix Willenbrink, marketing manager for footwear, sports and leisure at BASF Polyurethanes, said: "In order to achieve the goals of a circular economy, it is important to develop new systems that help preserve resources and reduce emissions in all phases of make-use-recycle. BASF is ready for the circular economy and a partner for sustainable sole production."
BASF has also launched a new generation of Infinergy E-TPU beads that can be processed into footwear components by heat press. This eases the manufacturing and provides a lower carbon footprint, it said.
Elastic coating solutions that protect and functionalise flexible surfaces in a wide variety of colours and effects will also be presented. NovaCoat-P is a post-mold coating solution to protect surfaces from various environmental influences. NovaCoat-D combines in-mold coating and release agent in a new way.
