SHANGHAI, April 20, 2026 /PRNewswire/ — Covation Biomaterials LLC (“CovationBio®“), a biomaterials company with advanced technology in the bio-based materials industry, announced today that its first commercial plant for the C4 product platform, including bioTHF and bio-based polytetramethylene ether glycol (“PTMEG”), achieved mechanical completion in April 2026. In addition, CovationBio now officially launches the Xatryx® brand for the portfolio of new, non-food, bioPTMEG products to be produced at the plant.
This milestone marks a significant step forward in defossilization of material production, reinforcing the company’s commitment to delivering high-performance, renewable-based solutions to the global market.
The C4 facility is located in Qidong, Jiangsu Province, China. It utilizes an innovative, new-to-the-world process technology developed by CovationBio. With a total investment of RMB 10 billion, the plant is planned in three phases, targeting a future total capacity of 500,000 tons per year of bio-based materials. The first phase, which is now mechanically complete, has a 50,000-ton-per-year commercial production capacity for both bioTHF and bioPTMEG. Commercial production is expected to begin in the second half of 2026.
Feifeng You, President of CovationBio, commented:
“The Xatryx® name conveys our spirit of relentless exploration to develop processes and products that deliver high performance and support defossilization of the materials industry. As an important building block, Xatryx® products provide many possibilities to improve one’s quality of life while taking good care of our planet. To achieve this, we leverage an abundant, non-food, agricultural by-product that is directly converted to a chemical feedstock, which our Advanced ThermoChemical technology uses to create Xatryx® products.”
A Sustainable Alternative to Fossil-Based PTMEG and not Competing with Food Sources
As a second-generation bio-based material, Xatryx® bioPTMEG serves as a drop-in replacement to fossil-based PTMEG, helping customers reduce their reliance on non-renewable materials while maintaining the high-performance of our downstream material applications such as spandex, polyurethanes, and thermoplastic elastomers.
Key sustainability benefits of Xatryx® bioPTMEG include:
- Substantial reduction of greenhouse gas emissions compared to fossil-based incumbents;
- Bio-based product made from annually renewable resources;-2nd generation bio-based feedstocks, such as corncobs, which do not compete with primary food sources;
- Reduced reliance on non-renewable fossil fuels;
- Drop-in performance to allow downstream customers to switch to bio-based raw materials without process changes.
Presence at CHINAPLAS 2026
Aligned with this year’s CHINAPLAS theme, “Transformation – Collaboration – Sustainability,” members of the CovationBio® team are ready to share more about how Xatryx® products can integrate into downstream materials and advance sustainability strategies with value chain partners. Visitors are invited to meet the team and learn more in Hall 1.2, Booth F77. For those interested in learning more, please contact: bioPTMEG@covationbio.com
