Materials and Method Materials for synthesizing polyurethane-urea foam included materials derived from natural fiber waste and chemicals.
SAC of Biofoam The factors affecting the high or low SAC value depend on the characteristics of the damping material owned, as follows [21], [22]: 1) density: high-density materials will have a higher SAC value than low-density materials; 2) texture: flexible/soft textured materials have a higher SAC value than rigid/hard textured materials, 3) microstructure: open-cell-type materials have a higher SAC value than closed-cell-type materials, 4) pore size: materials with small pores have a higher SAC value than materials with large pores.
