CovationBio Begins Mass Production of Bio-Based PTMEG for Footwear

Covation Biomaterials LLC (CovationBio), a developer of bio-based materials, has reached a major commercialization milestone with the successful production of its first on-spec commercial batches of Xatryx.T bioTHF and Xatryx® bioPTMEG. The company has also partnered with INSITE® to introduce an athletic insole made with Xatryx® bioPTMEG at the NW Materials Show in Portland, Oregon, marking the material’s transition from renewable feedstock to an end-use footwear component.

The production milestone follows the mechanical completion of CovationBio’s first 50,000-ton commercial plant for its C4 platform technology in April 2026. Four months later, the Qidong facility began producing its first commercial batches in August. These include Xatryx.T bioTHF and Xatryx® bioPTMEG grades with molecular weights of 2,000, 1,800, and 1,000. According to the company, all three grades successfully met expected industry quality specifications following extensive internal testing.

CovationBio Chairman You Feifeng said the company completed equipment commissioning, process optimization, and scale-up within four months. The successful production of multiple molecular-weight grades demonstrates the stability and maturity of the company’s proprietary process technology. CovationBio is now working with downstream customers on trial samples and gathering performance feedback to validate the materials and their compatibility with existing production processes.

Xatryx® bioPTMEG is positioned as a renewable alternative to conventional fossil-based PTMEG. The material can serve as a direct replacement in applications such as spandex, polyurethane and thermoplastic elastomers while maintaining downstream performance.

The technology offers several sustainability advantages. Its production is designed to generate lower greenhouse gas emissions than fossil-based alternatives, while its bio-based content comes from renewable, non-food biomass, including agricultural residues such as corncobs. This approach reduces dependence on fossil resources without competing directly with food production. Its drop-in capability could also allow manufacturers to adopt the material without significant modifications to existing processes.

At the September 2–3 NW Materials Show, CovationBio and INSITE® will jointly showcase a partially bio-based athletic insole incorporating Xatryx® bioPTMEG. The collaboration demonstrates the material’s potential in footwear and highlights growing efforts to integrate renewable materials into consumer products.

The companies said the collaboration represents an accelerated path from raw-material development to commercial end-use applications and could encourage broader adoption of non-food bio-based materials across the global materials industry.

Product Impact + Chemical Price Impact

The development is positive for bio-based PTMEG, bioTHF and sustainable polyurethane-related applications, as commercial-scale production improves availability and provides downstream manufacturers with a drop-in renewable alternative. The launch of a bio-based athletic insole could strengthen demand for Xatryx® bioPTMEG in footwear, spandex, polyurethane and thermoplastic elastomer applications. For chemical commodities tracked by ChemAnalyst, the immediate price impact on conventional PTMEG and THF is likely limited because the 50,000-ton facility is still entering commercialization. However, wider customer adoption could gradually increase competitive pressure on fossil-based PTMEG and potentially moderate its long-term demand growth, while supporting premiums for bio-based grades.
