In this study, the NR latex mixture was frothed to produce NR latex foam with the target foam density ranging from 0.8 g/cm3 to 0.14 g/cm3, which is considered firm NR latex foam. The presence of P.O. in the latex mixture as a foaming agent, as well as a foam stabiliser, is important because it reduces the surface tension during whipping of the NR latex mixture to introduce air. However, during the frothing process, the normal practice is to prevent the foam volume from exceeding seven times the initial volume of the NR latex mixture to avoid cracks and cavities in the final product. In this study, a 0.13 g/cm3 foam density was achieved, and thin (25 mm thick) moulded NR latex foam was
