Roles of Chitosan as Bio-Fillers in Radiation-Vulcanized Natural Rubber Latex and Hybrid Radiation and Peroxide-Vulcanized Natural Rubber Latex: Physical/Mechanical Properties under Thermal Aging and Biodegradability

Abstract: Although natural rubber was regarded as biodegradable, the degradation is a time-consuming process that could take weeks or months for any degradation or substantial weight loss to be observable, resulting in the need for novel processes/methods to accelerate the rubber degradation. As a result, this work investigated the potential utilization of chitosan (CS) as a biodegradation enhancer for radiation-vulcanized natural rubber latex (R-VNRL) and hybrid radiation and peroxide-vulcanized natural rubber latex (R… Show more

“…In particular, for natural latex gloves, the oxidative degradation during the process of product preparation, sterilization, and storage could noticeably reduce the usability and shelf-life of the gloves. For instance, the NRL films (without any antioxidants) suffered a great decrease in tensile strength from 13 MPa in a non-aged sample to less than 10 MPa in a thermal-aged sample (reduced by also 25%), which was lower than the requirement for latex gloves used in food and medical sectors [19]. This reduction in the mechanical properties was due to the lack of antioxidants in the samples that could convert free radicals into more stable products and end the degradation.…”
