Covation Biomaterials Showcases Key Developments for CovationBio® bioPTMEG at K-Show 2025

DÜSSELDORF, Germany, October 8, 2025 – Covation Biomaterials LLC, known by its brand CovationBio®, is at the forefront of innovation in the bio-based materials industry. During the world-renowned K-Show 2025, a leading trade fair for plastics and rubber, the company proudly presents critical milestones and updates regarding its latest advancement in sustainable materials: CovationBio® bioPTMEG.

The journey of CovationBio® bioPTMEG began with its initial announcement at the ChinaPlas event in April 2025. This advanced version of polytetramethylene ether glycol (PTMEG) is not just another product; it embodies a commitment to sustainability, featuring a significantly reduced emission profile compared to traditional fossil-based alternatives. As Feifeng You, President of CovationBio, remarked, “Through ongoing collaboration with our customers, we are achieving crucial milestones in making bioPTMEG commercially viable. This product redefines what is possible within the realm of bio-based materials.”

CovationBio® bioPTMEG serves as a bio-based substitute for its fossil-derived counterpart, promoting a lesser dependency on non-renewable resources while maintaining the robust durability and resilience demanded in applications such as spandex, polyurethanes, and thermoplastic elastomers. The advantages of this innovative material are noteworthy:

- Substantial Reduction of Greenhouse Gas Emissions: Compared to traditional fossil-derived PTMEG.
- 100% Bio-Based: Sourced from renewable resources, assuring a sustainable lifecycle.
- Renewable Feedstocks: It utilizes inputs like corncobs, whose cultivation does not impede food supply.
- Decreased Fossil Fuel Dependency: Minimizing reliance on non-renewable materials.
- Drop-In Performance: This allows downstream manufacturers to transition to bio-based raw materials with minimal changes in production processes.

In conjunction with its product unveil at K-Show, Covation Biomaterials is excited to announce the construction of a specialized manufacturing facility for CovationBio® bioPTMEG. Set to be mechanically complete by the end of 2025, this facility is located in Qidong, Jiangsu Province, with commercial production slated to commence in the first half of 2026.
