Influence of sodium-montmorillonite nanoclay on flammability, thermal stability, morphology, and mechanical properties of rigid water-blown palm oil-based polyurethane foam

This paper presents the experimental works on rigid palm oil-based polyurethane (PU) foam reinforced with sodium-montmorillonite (Na-MMT). Filler loading was varied between 1 and 10 wt %., and the obtained foam was characterized for its combustibility, morphology, thermal stability, and mechanical r...
