Abstract: Plaster and stoneware hand moulds were fabricated and used in the NR latex glove preparation. The raw materials characteristics combined to influence the hand mould surface properties through the adhesion-cohesion force, interfacial tension, contact angle, packing density. The stoneware hand mould fired at 800°C, fabricated from a smaller particle size distribution, with high zeta potential and interfacial interaction, and high specific surface area was shown to be superior to the plaster hand mould typically used in making NR latex products. The obtained NR latex films were characterised for various physical properties, namely appearances, thickness, tackiness, porosity, smoothness, optical clarity, and effusion.

Keywords: stoneware hand moulds; natural rubber gloves; adhesion-cohesion force; interfacial force; surface properties; mechanical properties; physical properties; natural rubber latex; dipping process.
