Description
Summary:The finished product natural rubber latex gloves consist of latex proteins, which may pose a risk of allergic reactions in some latex-sensitive individuals. The allergic reactions depend on mild exposure to heavy exposure. An alternative solution to allergic users, usage of latex-free gloves are lack of elasticity and less comfort. This study aims to investigate natural rubber films protein reduction via three types of leaching solvent: acetic acid, sodium hydroxide, and ethanol in the leaching process. Then the influence of leaching solvent concentration on the physical properties of natural rubber gloves was analyzed. It was found that the acetic acid performed greater protein reduction effect (30.07%), followed by sodium hydroxide (27.77%), whereas the ethanol was shown to be less significant to protein reduction. All samples were fulfilling the mechanical properties as required in ASTM standard.
