Dow claims new polyurethane supports renewable resources in footwear

21/12/2011
Chemicals manufacturer Dow has announced a new renewable polyurethane (PU) material that it believes will be of interest to footwear manufacturers. Under the name Green Footprint Project, the company will launch the new product in the first quarter of 2012.

The project is the result of a partnership between Dow and Italian soling materials manufacturer Mondialsuole and is part of the wider LIFE+ programme that has funding from the European Commission to support environmental and nature conservation projects throughout the European Union. The Green Footprint project qualifies because it uses bio-based Dow polyurethane systems that feature Voralast renewable resources technology.

Voralast solutions are based on polyester polyols that contain renewable raw materials. Renewable content can easily reach up to 30% by weight on average and can achieve up to 35% of the total weight.
According to Dow, they can mean 54% lower global warming potential for PU soles, around 25% lower cumulative energy demand for the raw polyol, reduced fossil fuel usage of up to 25%, energy savings of 13% and reduced carbon footprint of up to 50%.
