Covestro said the materials' properties mean that they can be processed at lower thicknesses, and the foams can pass FMVSS302 flammability testing.
Covestro's chief commercial officer, Sucheta Govil, said: 'We are now taking another important step towards using carbon dioxide as an alternative raw material in the chemical industry on an even broader scale.'
'Novel materials like Cardyon are extremely important for the development and responsible production of sustainable foams,' FoamPartner's CEO Michael Reidel said. He added that the materials have superior functionality over conventional ether-based PU foams.
FoamPartner estimates that the sustainable share in the final foam is 13%.
As they have good hydrolytic stability, FoamPartner said the OboNature foams would be aimed at electric and hybrid vehicles.
Covestro said Cardyon has also been used in elastic textile fibres. It is also working with a number of textile manufacturers to bring fibre production to industrial scale, and novel fibres to market.
