Biobased epoxy polymeric materials are called to progressively replace fully synthetic ones aspetroleum scarcity becomes a more visible problem and its price continues to rise. Considerable efforts are being undertaken by both academic and industrial actors to reach reliable biobased products with competitive properties to alleviate the dependence on fossil resources and to facean increasing demand on more environmentally friendly materials. The previous chapters of this book covered several aspects and the assessment of relevant properties of biobased epoxy materials. In this chapter we focus on three appealing applications of biobased epoxies: selfhealing thermosetting polymers and composite matrices, with special emphasis on the recently developed self-healing and recyclable networks based on dynamic and reversible bonds; pressure sensitive adhesives, whose growing market, together with increasing restrictions on the use of fossil-derived precursors make an ideal opportunity for biobased epoxies; finally, the most relevant applications for epoxy foams, both syntactic and those obtained through a foaming process, are described and discussed.
