Abstract: This paper examined the synthesis of hyperbranched polymers (HBPs) and how their hydroxyl end groups help form networks in tannin-based foams. A thermal analyzer (TPS) measured the thermal conductivity of the foam samples using the transient plane source (TPS) method. Results showed that modified foams retained their thermal insulation properties even with the addition of oligomeric precursors. This gives good indication that the addition of hydroxyl-terminated oligomeric precursors to tannin based foams can boost the foam network without affecting thermal conductivity or fire resistance, so the materials can be used in a wider scale of applications.
