Emery Oleochemicals has introduced Emerox renewable and Infigreen recycled polyols as part of its range of eco-friendly polyols for flexible polyurethanes. These have potential applications in the automotive sector where OEMs are increasingly demanding green alternatives to conventional materials.
Emerox polyols are produced via Emery Oleochemicals’ proprietary ozonolysis technology. InfiGreen polyols are aromatic polyether/ester polyols, produced via our proprietary chemical process that uses scrap polyurethane foam as the key raw material.
In this paper, the performance characteristics of Emerox and Infigreen polyols are demonstrated as a partial drop-in replacement for conventional polyether polyols in resilient TDI-based flexible polyurethane foams. The impacts of Emerox and Infigreen polyols are evaluated on the foaming reaction profiles and on the key physical properties of free-rise and moulded high resilient polyurethane foams.
Emery Oleochemicals started working on ozonolysis of fatty acids, with commercial implementation in the 1960’s. Emerox polyols can be produced from several types of natural oils to yield bio-polyols with the possibility of a high level of polyol structure customization and improved consistency over existing natural oil polyols (NOPs). This should enable higher incorporation levels in polyurethane applications.
Automotive consumers are increasingly expecting their cars to be greener, and these renewable or…
