Overview

Randomized trial demonstrates rapid foaming and low thermal conductivity in biobased epoxy foams, suggesting a sustainable alternative to harmful materials.

Key Points

  • This research aims to develop sustainable, biobased alternatives to harmful polyurethane foams for thermal insulation.
  • Optimized a biobased epoxy–amine system using glycerol triglycidyl ether and triethylenetetramine for rapid foaming at room temperature.
  • Investigated various factors like prepolymer composition, water content, and type of physical blowing agents.
  • Conducted experiments to analyze foaming kinetics and foam morphology.
  • Foams expanded rapidly in under 10 minutes with densities of 90–160 kg.m –3.
  • Achieved a notable low thermal conductivity of 47 mW·m –1 ·K –1 for methyl acetate-blown foams.
  • Demonstrated the feasibility of producing viable biobased epoxy foams under mild conditions.
