Mousses rigides de tannins de type procyanidine : formulation et caractérisation

Abstract : Rigid foams contitute a very important class of materials considering their wide application range and their considerable economic impact. The development of tannin-based foams provided materials made from 90% natural products.In this work, a type of tannins highly reactive, namely « procyanidin », was used. First, tannins composition and reactivity were studied. Then, the foaming process investigation of tannin-based resins leads to a wide pannel of tannin-furanic rigid foams. Their excellent fire resistance, mechanical resistance and high thermal performance make them high quality insulation materials. These foams are also suitable for other applications such acoustic absorption. Thus, new cellular solids from tannin and protein were also developped, offering a new type of materials derived from natural products
