A preliminary study was made on the effects of some additives on the properties of palm-based polyurethane foam, such as density, hardness and curing time. The additives – Ethacure 100, Ethacure 300, Amisol CDE and KD-1, N-methyl-2,2′-iminodiethanol (MDEA) and phthalic anhydride – were incorporated into the polyurethane foam by mixing with blended polyols (40 g palm-based polyol with 60 g petro-based polyol) and MDI (4,4′-diphenylmethane diisocynanates) and 2.3 g water used as the blowing agent. Incorporating 5 ppH Ethacure 100 and 10 ppH Amisol (either CDE or KD-1) substantially increased the density of the foams from 264 kg m-3 to 398.28 kg m-3 and the hardness from 34.5 to 55 shore D, while the demoulding time was decreased from 20 min to less than 5 min
