Recycling of waste rubber gloves is an alternative to sustainable methods in ensuring that waste rubber does notpile up. The main focus of this investigation is to evaluate the potential of utilising waste rubber gloves as fillers inunsaturated polyester-based composites. The evaluation also studies the effect of different loading of rubber content towardsthe composite’s mechanical properties with 8 different rubber contents being considered. Rubber contents of 5, 10, 15, 20, 25,30, 35 and 40 wt. % have been studied in this work. Waste rubber gloves were ground into crumbs using cryogenic grindingand added into the unsaturated polyester. The composite is characterised for its tensile and flexural strength, elastic modulus,impact strength and fracture surface morphology. The addition of rubber crumbs has increased the toughness of thecomposite while it decreased the tensile strength, flexural strength and elastic modulus. Due to rubber hydrophobicbehaviour, adhesion between rubber crumbs and polyester gets weaker as the rubber content was increased, therefore thetensile strength of the composite dropped. The SEM micrographs of the tensile fracture surface of the composite revealed thatvoids in the composite increases as the rubber content is increased. Voids occur due to inhomogeneous distribution of rubbercrumbs throughout the composite.
