Cardolite offers a comprehensive polyol and diol product line with most materials having renewable content from cashew nutshell liquid (CNSL). Those materials deliver unique performance compared to widely known polyester and polyether polyols, and other natural oil based polyols.
Many properties are inherited from the CNSL backbone. The long aliphatic side chain brings in hydrophobicity which translates into low moisture sensitivity during cure with isocyanate. The aromatic ring provides fire and thermal resistance, as well as chemical resistance and hydrolytic stability. The combination of aromatic and aliphatic content promotes a good balance in mechanical properties and reactivity. Moreover, CNSL-based polyols and diols can be designed and functionalized to achieve a wide range of properties according to end-use applications.
Cardolite renewable polyols and diols are suitable for one- and two-component polyurethane coatings, adhesives and sealants, elastomers and rigid and flexible foams. To learn more, please visit our polyols and diols technology page or product line page.
