|First thermoplastic polyurethane based on CO2 technology
• New polyols reduce carbon footprint
Under the name cardyon™, Covestro is developing and marketing new polyether carbonate polyols that are produced with the aid of carbon dioxide (CO2). With Desmopan® 37385A the company now offers the first representative of a new series of thermoplastic polyurethanes (TPU) containing polyether carbonate polyols based on CO2 technology.
Compared to conventional TPU materials, the new TPU products leave a lower carbon footprint and help close the carbon cycle. They also conserve fossil resources and, unlike many bio-based materials, do not compete with food production.
“With the new TPU, our customers can reduce the carbon footprint of their products and as a result play a pioneering role in sustainability vis-à-vis their competitors,” explains Georg Fuchte, TPU expert at Covestro. “This is especially true for companies in the consumer goods industry, which often manufacture products with a short lifespan.”
Excellent mechanical properties
Different product variants
Covestro cooperates closely with companies and research institutions to use CO2 technology as a synthesis platform for other large-scale chemical raw materials. For example, work is underway on new CO2-based polyols for rigid polyurethane foams that could be used, for example, in the thermal insulation of buildings, in automobiles and in sports equipment. At the Dormagen plant, Covestro already operates a production plant that produces CO2-based polyols for flexible polyurethane foams. The latter are used in the commercial production of upholstered furniture and mattresses.

Surface structure: The outstanding imaging accuracy of TPU products of the Desmopan® series has been established for decades. Unique surface structures can be created by using different technologies. Covestro is currently working together with its partner J. & F. Krüth in Solingen to open up almost unlimited possibilities for surface design with the help of innovative and fully digital 3D laser engraving.
