Covestro's family of partially bio-based thermoplastic polyurethanes (TPU) is now marketed under the name Desmopan® EC. Depending on the product hardness, up to 60 percent of the carbon content1 is derived from biomass. Compared to fossil-based TPUs, their carbon footprint is reduced by more than 20 percent. The products are made of bio-based succinic acid as well as bio-based propanediol (Bio-PDO). The plastics have a wide range of applications, for example in the footwear industry.

Product line of partially bio-based TPUs now called Desmopan® EC

"Covestro intends to gear its entire production and product range completely to the circular concept in the long term," says Dr. Thorsten Dreier, Global Head of Covestro's TPU and films business. "An important aspect of this program is the increased use of alternative raw materials, for example from biomass – which is consistent with our customers' wishes."

The partially bio-based grades feature the same good quality and performance as previous products in the Desmopan® range and offer equally superior resistance to oils, fats, solvents, weathering as well as high-energy radiation. In addition, a grade certified with the BLUESIGN seal is available for particularly responsible and sustainable textile production.

Thermoplastic polyurethanes offer high wear resistance and flexibility over a wide temperature range. In addition, the material is soft and elastic, eliminating the need for plasticizers. Desmopan® brand TPUs consist of linear polymer chains with alternating flexible and rigid segments. By modifying these phases, properties such as hardness, strength, stiffness, elasticity and low-temperature flexibility can be varied over a wide range.

Covestro, FILK Freiberg, and OUT e.V. develop flexible, conductive polymer smart textile system

As the smart textiles market continues to grow across healthcare, personal protection, sportswear, and automotive applications, developers are seeking new ways to integrate electronic functionality directly into textiles, without the rigidity and complexity of conventional wiring. To address this challenge, FILK Freiberg Institute, an independent research institution with expertise in polymer coatings for textile applications, collaborated with Optotransmitter-Umweltschutz-Technologie (OUT) e.V. The joint project, funded under the German Industrielle Gemeinschaftsforschung (IGF) program of the Bundesministerium für Wirtschaft und Energie (BMWE), focused on developing flexible, conductive polymer surfaces for next-generation smart textiles.

Covestro to exhibit solutions for a more sustainable and productive textile industry at Techtextil 2026

Covestro will present a broad portfolio of material innovations for textile coatings, adhesive films and thermoplastic polyurethanes (TPUs) at Techtextil 2026 (Hall 11.0, Booth C79). The exhibits will demonstrate how advanced solutions can enhance durability, recyclability and manufacturing efficiency across applications such as automotive, infrastructure, protective apparel and sportswear. A particular focus will be on more sustainable coating technologies, including antimicrobial systems based on INSQIN® in combination with AGXX from Heraeus Precious Metals, as well as the integration of Pontacol® thermoplastic adhesive films into Covestro’s offering.

Covestro showcases monomaterial concept in autonomous SUE People Mover

UE | STUDIOS has unveiled the fully autonomous electric minibus “Self-driving Urban E-Shuttle” (SUE), placing strong emphasis on sustainable material design. Developed within a project funded by the Federal Ministry for Economic Affairs and Energy (BMWE) and the European Union, the vehicle will begin public road testing this year. At the core of the concept is the consistent use of recyclable monomaterials to improve circularity at end of life.

Covestro and Heraeus Precious Metals collaborate to enable safer, more sustainable antimicrobial textile coatings

Laboratory tests reveal that AGXX antimicrobial surface technology from Heraeus Precious Metals is fully compatible with Impranil® PU dispersions which are part of the waterborne INSQIN® textile coating technology from Covestro, paving the way for more sustainable antimicrobial textile coatings. This discovery comes at a key moment for the textile coatings industry. As the sharing economy continues to grow, more people are coming into regular contact with high-use surfaces, creating ideal conditions for bacteria, viruses, and other microorganisms to thrive.
