Covation Biomaterials, a biomaterials company with advanced bio-based technology, has shared project updates at K 2025, the world’s top plastics and rubber trade fair.
First announced at ChinaPlas in April 2025, CovationBio® bioPTMEG is a new, sustainable polytetramethylene ether glycol (PTMEG). It offers high performance with significantly lower emissions than fossil-based options.
“Working closely with our customers, we are making great progress,” said Feifeng You, President of CovationBio®. “Our bioPTMEG is a sustainable, high-performance product. It has the lowest environmental impact and redefines what biobased materials can do.”
CovationBio® bioPTMEG is a bio-based alternative to traditional PTMEG. It helps customers reduce reliance on non-renewable resources while maintaining durability and resilience for high-performance applications like spandex, polyurethanes, and thermoplastic elastomers.
This innovative product offers numerous sustainability benefits. It significantly reduces greenhouse gas emissions compared to fossil-based products, providing a more environmentally friendly option. Made from 100% renewable resources, it utilizes feedstocks such as corncobs, which do not compete with food supplies. This reduces reliance on non-renewable fossil fuels and supports a circular economy. Additionally, bioPTMEG offers drop-in performance, allowing customers to switch to bio-based raw materials without major process changes.
As announced at ChinaPlas 2025, a dedicated manufacturing facility for CovationBio® bioPTMEG is under construction in Jiangsu Province, Qidong. The plant is expected to be mechanically complete by late 2025, with commercial production beginning in the first half of 2026.
Aligned with this year’s K Show theme, “The Power of Plastics! Green – Smart – Responsible,” the Covation Biomaterials team will showcase how bioPTMEG can be integrated into high-performance materials such as TPU, PU, COPE, COPA, and spandex. Their goal is to advance sustainability strategies across multiple applications in partnership with the industry.
