Effect of aluminium hydroxide loading on the compression stress and modulus, thermal conductivity and acoustic properties of palm-based polyurethane hybrid composite

The effect of adding aluminum hydroxide (ATH) in the palm-based polyurethane hybrid composite was studied. The compression stress and modulus, thermal conductivity and acoustic property were determined. The hybrid composite was prepared by adding 10 wt% of oil palm empty fruit bunch fibre (EFB) foll...
