Structure-property relationships of TPUs from bio-based C18 polyester polyols

摘要

Polyurethanes may display thermoplastic, elastomenc and thermoset behaviour, depending on their structures and morphology. As a result of the diversity of mechanical, physical, biological and chemical properties that are available, polyurethanes are widely used as rigid foams, flexible foams, coatings, adhesives, sealants and elastomers (CASE). This work shows that Elevance Inherent CI8 Diacid can be reacted with different diol co-monomers to produce polyols with a wide range of morphologies. These can be used to produce polyurethanes for many applications. There is a growing demand from customers for materials with good properties that are made sustainably. Inherent CI8 diacid is made from completely biorenewable carbon, and the corresponding CI8 polyols range between 61-100%, depending on the source of the diol co-monomer(s).
