Ruixun Biomaterials Completes Mechanical Completion of First Commercial-Scale Bio-Based THF and PTMEG Plant, Launches New Brand

April 20, 2026, Shanghai, China——Ruixun Biomaterials Co., Ltd., a leading company in the bio-based materials industry

（"CovationBio^® "announced that its first commercial production base for the C4 platform, including bioTHF (bio-based tetrahydrofuran) and bioPTMEG (bio-based polytetramethylene ether glycol), will achieve mechanical completion in April 2026,"

and officially announced the upcoming production of a new non-food-based bio-material at this facility.PTMEG product brand Xatryx^®。

This milestone marks a significant step for Ruixun Biology in the production of fossil-fuel-free materials, demonstrating the company's commitment to providing high-performance renewable solutions to the global market.

The facility, located in Qidong City, Jiangsu Province, employs proprietary process technology independently developed by Ruixun Bio. With a total investment of RMB 10 billion, the plant is planned for construction in three phases, targeting a total annual production capacity of 500,000 metric tons of bio-based materials. The Phase I commercial production project, with an annual capacity of 50,000 metric tons of bioTHF and bioPTMEG, has now reached mechanical completion and is expected to commence its first production in the second half of 2026.

Mr. You Feifeng, Chairman of Ruixun Biomaterials, stated:

“Xatryx^®It embodies our relentless pursuit of excellence in process and product development, achieving outstanding performance while helping the materials industry move away from fossil-based products. As a critical foundational material,Xatryx^®In enhancing the quality of life, there are abundant possibilities, while also carefully protecting our Earth. To achieve this goal, we make full use of the rich non-food agricultural by-products, converting them directly into chemical raw materials, and then through advanced thermochemistry.ATC technology is used to prepare Xatryx^®Product."

fossil-basedSustainable alternatives to PTMEG, not competing with food sources

As the second-generation biobased material,Xatryx^®Directly replace fossil-basedPTMEG not only helps customers maintain excellent product performance in downstream material applications such as spandex, polyurethane, and thermoplastic elastomers, but also reduces reliance on non-renewable materials.

Xatryx^®Bio-basedThe core sustainable advantages of PTMEG include:

Reduces greenhouse gas emissions compared to fossil-based counterparts;

Bio-based products, whose raw materials are derived from annually renewable resources;

Using second-generation bio-based raw materials, such as corn cobs, without competing with staple food.

Effectively reduced dependence on non-renewable fossil fuels;

Can be used directly, enabling downstream customers to switch to bio-based materials without adjusting their main processes.
