Description
A solid foam designed using natural plant based materials. Biobased foams often mimic the cellular structure of wood. These porous, lightweight materials typically manufactured using cellulose fibers dispersed in a foaming agent or gel such as cellulose ester, or methyl cellulose. The biobased foams should be recyclable with cardboard. These cellulose foams exhibit antimicrobial properties, mechanical anisotropy, and high thermal insulation. Some alternatives are using wheat gluten for the gel formation in order to produce flame-retardant materials.
