Thermal Stability of Phenolic Foams

Eco-foaming lignin for innovative rigid foam

“…Foam samples with lower densities exhibit higher porosity but lower compressive strength and Young's modulus. 18 Compared to commercial foam pro- ducts, the density and compressive strength of the lignin foam samples are also higher than those of commercial polystyrene (PS) foam 19 and are comparable to the phenolic-based polyurethane (PU) foam 20 (Table S4 †). Moreover, the foam samples showed good thermal insulation properties (Table 1 and Table S4 †).…”
