Covation prepares to launch corn-based precursor for elastane
19/01/2026
The company has set up a manufacturing facility for bioPTMEG in Jiangsu Province, Qidong. Commercial production should begin in the first half of this year. PTMEG is used as one of the building blocks for elastane.
CovationBio CEO Steven Ackerman said: “We’re excited about the opportunity to commercialise solutions that reduce friction for our downstream value chain partners as they look to integrate sustainable materials into their production. As a drop-in replacement for traditional PTMEG, bioPTMEG can be seamlessly integrated as a bio-based raw material option without major process changes.”
In 2022, Huafon Group bought DuPont Biomaterials and launched Covation Biomaterials. Covation makes Sorona, a 37% plant-based polymer used in wovens, knits, insulation and footwear; and Susterra, a 100% plant-based diol ingredient used in footwear, outdoor apparel and performance gear.
Lycra and Hyosung have made large investments in switching their BDO over to bio-based sources – industrial corn and sugar cane respectively – which helps reduce the carbon footprint of the elastane.
