dc.description | This study compares the physicochemical and spectroscopic characteristics, resistance tothermooxidation, and processability of natural rubber cup lumps of clones IAN 873 and FX 3864 withthose of technically specifed grade 10 natural rubber from Guatemala—one of the most commonlyimported rubbers in Colombia and Latin America. Additionally, processing characteristics associatedwith energy consumption were determined through torque rheometry. Therefore, compounds wereformed using a semi-efcient vulcanization system. Further, rheometric properties and vulcanizationparameters were measured at 160 °C in a moving die rheometer. Moreover, these measurementswere used to vulcanize the standardized samples and to test stress and hardness properties basedon the Shore A scale. The cup lumps were found to have a higher gel content, which affected the vulcanization reaction of the compounds; however, signifcant differences were found neither in internalmixer processing characteristics nor in the technological properties of the vulcanized compounds.These results reveal that cup lumps represent a technically viable alternative for the production ofnatural rubber products. | en-US |
dc.description | En este artículo, se compararon propiedades fsicoquímicas, espectroscópicas, de resistencia a la termooxidación y de procesabilidad de fondos de taza de caucho natural de los clonesIAN 873 y FX 3864 respecto del caucho natural técnicamente especifcado grado 10 proveniente deGuatemala, uno de los más importados en Colombia y en América Latina. Se determinaron tambiénsus características de procesamiento en reómetro de torque asociadas al consumo de energía. Seelaboraron compuestos con un sistema de vulcanización semiefciente y se evaluaron propiedadesreométricas y los parámetros de vulcanización a 160ºC mediante reometría de disco móvil, con losque se efectuó la vulcanización de probetas estandarizadas para la evaluación de propiedades entensión y dureza Shore A. Se encontró que los fondos de taza presentaron un mayor contenido degel, lo que tuvo un efecto en la reacción de vulcanización de los compuestos; no obstante, no seencontraron diferencias signifcativas en las características de procesamiento en mezclador internoni en las propiedades tecnológicas de los compuestos vulcanizados. Estos resultados muestran quelos fondos de taza representan una alternativa técnicamente viable para la fabricación de productosen caucho natural. | es-ES |
