Korean scientists have developed TPU with a bio-based content of up to 97%

Scientists at the Gyeongbuk Institute of Science and Technology in Daegu, South Korea, have found a way to make thermoplastic polyurethane (TPU) with a bio-based content of 97%. It is made using biomass monomers instead of petroleum-based materials. This TPU is made from sebacic acid polyester polyol, 1,4-butanediol and isocyanate using a one-shot polymerization process.…
