Dow's Recycled Polyurethane Solutions

Applying the power of collaboration, we’ve engaged with leading automotive suppliers Adient, a market leader for seating in the automotive sector, and Autoneum, the leading acoustics and thermal management supplier, to tap into the potential of the mass balance approach for our SPECLEX™ Circular Series. Both companies are incorporating SPECFLEX™ Circular into their existing products without having to adapt formulations or processes. Together, we can transition to a low carbon mobility.

Recycled content and improved lifecycle analysis

By using circular feedstocks, Dow provides a range of solutions for products with up to 55% recycled content and an improved lifecycle analysis profile compared to fossil-based fuel. 

Circular mobility solutions

SPECFLEX™ Circular Series reduces our dependence on fossil fuels through circular mobility solutions without any loss in quality or performance.

Circular feedstock sourced from recycled raw materials

Our SPECFLEX™ Circular Series uses a circular feedstock sourced from recycled raw materials of the mobility sector to enable a wide range of flexible foam solutions for comfort and acoustic purposes in interior, exterior, as well as powertrain solutions in consumer and transportation applications.

Closing the loop

By using circular feedstocks instead of virgin fossil-fuel based ones, SPECFLEX™ Circular products reduce our carbon footprint (carbon calculations follow ISO 14044*) and promote automotive sustainability throughout vehicle lifecycles.

*PCF calculated based on ISO14044/ Together for Sustainability - Gold Standard for the Chemical Industry: Waste treatment and recycling system.

Produce, use, and retire sustainably

The basis for mobility innovation begins at the design phase and choosing the right raw materials is key to addressing automotive sustainability challenges. Our polyurethane innovations are designed to help customers reach their goals as well as meet their market and regulatory demands for more circular products. Let’s drive the future of automotive sustainability forward.
