Abstract
Use of at least one procyanidin- and/or prodelphinidin-type tannin, devoid of prorobinetidin- and/or profisetinidin-type tannin, in a mixture with furfuryl alcohol for the implementation of a polymerization reaction for the preparation of rigid foams, said procyanidin- and/or prodelphinidin-type tannin being in particular pine bark tannin.

Use of at least one procyanidin- and/or prodelphinidin-type tannin, devoid of prorobinetidin- and/or profisetinidin-type tannin, in a mixture with furfuryl alcohol for the implementation of a polymerization reaction for the preparation of rigid foams, said procyanidin- and/or prodelphinidin-type tannin being in particular pine bark tannin.
Rigid foam comprising at least one procyanidin- and/or prodelphinidin-type tannin, polymerized with furfuryl alcohol and devoid of prorobinetidin- and/or profisetinidin-type tannin polymerized with furfuryl alcohol, said tannin being in particular pine bark tannin.
