Changhua Chemical is to commercialise a range of polycarbonate ether polyols derived from carbon dioxide under the Carnol brand. Pilot samples are now available for qualification and development ahead of the polyols’ expected launch later in 2025.
The polyols are manufactured using Econic’s catalyst and proprietary process, with the CO2 coming from industrial waste. Ground was broken for the production facility in June 2025, and the polyols are now being used for the continuous production of CO2-based flexible foam at a pilot scale.
Changhua said that the combination of carbonate and ether bonds in the Carnol polyols gives good resistance to both hydrolysis and yellowing in the resulting foam. The company said it has broad application potential in the automotive sector, including interior surface composites, moulded seats, carpets and headrests. It can also be used in home furnishing products, such as mattresses, pillows and sofas.
“The successful production of Carnol polyether’s first CO2-based foam marks a major breakthrough in green, low-carbon materials and their application technologies,” the company said. “We will work hand in hand with our customers and global partners to forge a zero-carbon future, making technological innovation the core driving force behind sustainable development worldwide.”
