  • Rigid foam with improved insulating power
    Patent number: 11718703
    Abstract: A rigid foam or composition allowing a rigid foam to be obtained made from polyurethane and/or polyisocyanurate. The rigid foam or composition includes polyols selected from polyester polyols and polyether polyols; the polyols include: 5 to 50% of a polyester polyol A by weight relative to the total weight of the polyols; and a polyol B selected from polyester polyols B and polyether polyols B. The polyester polyol A is of general formula Rx-Ry-Z-Ry?-Rx? in which Z is a C3 to C8 alcohol sugar chosen from glycerol, sorbitol, erythritol, xylitol, araditol, ribitol, dulcitol, mannitol and volemitol. Ry and Ry? are diesters of formula —OOC—Cn-COO— in which n is between 2 and 34, and Rx and Rx? are identical or different C2 to C12 monoalcohols.
