Cardolite offers a line of renewable, cashew nutshell liquid (CNSL) based polyols that have unique qualities compared to widely known polyester and polyether polyols, and other natural oil based polyols.
CNSL polyols are very hydrophobic because of the long aliphatic chain of cardanol, the absence of ester bonds (hydrolyzable), and fewer ether oxygen atoms compared to typical polyether polyols (less hydrophilic).
