The maximum difference of the core density distribution is only 1.6 kg/m 3. The foam achieved compressive strength (10% deflection) of 170 kPa, thermal conductivity of 0.0191W/(m·K), dimensional stability of 0.21%, at core density of 35.6 kg/m 3.The result shows that this system meet the production and property requirement of appliance application.
