This paper aims to show that it is possible to produce in a few minutes lightweight and rigid foams using molecular platforms derived from vegetable oils. The concept proposed involves first two epoxy compounds with differentiated reactivity versus a cycloaliphatic diamine (IPDA). Then, by the progressive substitution of ELO by EG units, highly reactive ternary formulations can be obtained with possible low gel time values and high thermomechanical properties whereas binary mixtures seem of lesser interest for industrial applications. By adding to these ternary formulations, some sodium bicarbonate acting as temperature activated blowing agent and a mineral compound playing the role of exothermicity regulator, it is possible to produce lightweight, rigid and non-carcinogenic foams in a few minutes. Thanks to theirs characteristics, these materials are already identified as potential candidates for future application in automotive manufacturing. Actually, the concept developed in this paper presents an interesting versatility. Indeed, by changing the nature and/or quantity of each compound present in the initial chemical formulation, the development of a comprehensive range of biomass-derived epoxy foams could be foreseen with wished specific characteristics (Tg, stiffness, density, morphology…). However, it is important to keep in mind that many reactions have to obey to equilibrium rules but it is possible to optimize them with a rigorous scientific approach.
