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 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.

Covestro celebrates decade of innovation and sustainable growth

Covestro celebrates its 10-year anniversary today. Since its carve-out from Bayer in 2015, the company has developed into a global leader in high-performance polymer materials and a pioneer in circular economy solutions. With a strong focus on innovation and sustainability, Covestro’s materials are now embedded in countless applications worldwide – from mobility and construction to electronics, healthcare, and consumer goods.

Jeanologia urges industry to accelerate PP Spray phase-out following ZDHC Watchlist update

Potassium permanganate has officially entered the Chemical Watchlist of the ZDHC Foundation, signaling increased scrutiny and potential phase-out of one of the most hazardous chemicals still used in denim finishing. The inclusion confirms an industry shift that Jeanologia anticipated more than a decade ago.

RUDOLF gets the exclusive global distribution rights for Sanitized® textile technologies

With effect from today, RUDOLF officially assumes exclusive global distribution rights for Sanitized® textile technologies from SANITIZED AG. This is the next milestone in the strategic collaboration announced in 2025, with the partnership between the two companies now fully implemented and expanded worldwide.

organIQ seek: smart alternative to potassium permanganate

CHT Group announces new technical findings within its organIQ seek platform that significantly advance the transition toward permanganate-free denim bleaching. Through extensive industrial testing and application research, CHT confirms that organIQ seek can now be used with remarkable effectiveness as a substitute for potassium permanganate in spray bleach, while remaining aligned with sustainability expectations and cost realities in the European market. At the COLOMBIATEX in Medellín as well as at the Exintex in Puebla and the Kingpins Show in Amsterdam the CHT Group will present organIQ seek as an alternative to potassium permanganate.

DIENES at Techtextil 2026: Flexible pilot lines for bio-based fiber development

The growing relevance of bio-based materials in technical textiles is accompanied by increasing demands for reproducibility, high-quality data, and scalable process routes. Especially when working with cellulose and its derivatives, chitosan, lignin-based approaches, or bio-based PAN as a carbon-fiber precursor, R&D teams face variable feedstock quality, tighter process windows, and the need for reliable comparability across trials. This calls for flexible, data-driven experimental setups that can be reconfigured efficiently when recipes, solvents, and raw-material batches change.

Gunold showcases embroidery product range and services at Texprocess

At Texprocess 2026, GUNOLD will present numerous hands-on examples related to embroidery in Hall 8, Booth E20.
