Loading effect of aluminum hydroxide onto the mechanical, thermal conductivity, acoustical and burning properties of the palm-based polyurethane composites

Effects of aluminium hydroxide (ATH) addition on the properties of palm-based polyurethane composites were investigated. The hybrid composites were prepared by mixing 10 wt% of oil palm empty fruit bunch fiber (EFB) with ATH at varying amount of 2, 4 and 6 wt% of the overall mass of the resin. The c...
