| dc.description.abstract | El presente informe técnico aborda la importancia de la estabilidad térmica en el policloruro de vinilo (PVC) y la creciente necesidad de optimizar la eficacia de los estabilizantes térmicos, especialmente en el contexto de la creciente conciencia ambiental. Se destaca la versatilidad del PVC en una amplia gama de aplicaciones, impulsando la demanda global y, simultáneamente, los desafíos ambientales asociados. El objetivo principal es presentar un modelo para determinar el comportamiento de la estabilidad térmica de mezclas de PVC ante la inclusión de estabilizantes térmicos biobasados, considerando variables como la parte orgánica, el metal estabilizante y la temperatura. Se enfatiza la importancia de establecer relaciones claras entre la dosis de estabilizante y el tiempo de vida estimado de los productos de PVC, abordando tanto la eficacia técnica como los impactos ambientales. La construcción de los modelos se basó información teórica y datos experimentales reportados, esta integración contribuyó a una representación más precisa de la estabilidad térmica de mezclas de PVC con estabilizantes térmicos biobasados, según la información encontrada, se generaron modelos para el análisis del comportamiento de estabilizantes derivados de Mirceno y de Aceitre de Semilla Caucho (RSO). Los modelos desarrollados proporcionan una base para futuras investigaciones y aplicaciones prácticas en la mejora de la estabilidad térmica en productos de PVC que involucren estabilizantes biobasados, se debe tener en cuenta que para utilizar de manera correcta estas herramientas de formulación se debe determinar el tipo de parte orgánica y metal que formen el complejo estabilizante, ya que, dependiendo de ello, los valores establecidos en el modelo deberán variar. | spa |
| dc.description.abstractenglish | This technical report addresses the importance of thermal stability in polyvinyl chloride (PVC) and the growing need to optimize the effectiveness of thermal stabilizers, especially in the context of increasing environmental awareness. It highlights the versatility of PVC in a wide range of applications, driving global demand and, simultaneously, the associated environmental challenges. The main objective is to present a model to determine the thermal stability behavior of PVC blends upon the inclusion of bio-based thermal stabilizers, considering variables such as organic part, stabilizing metal and temperature. The importance of establishing clear relationships between the stabilizer dosage and the estimated lifetime of PVC products is emphasized, addressing both technical efficiency and environmental impacts. The construction of the models was based on theoretical information and reported experimental data, this integration contributed to a more accurate representation of the thermal stability of PVC blends with bio-based thermal stabilizers, according to the information found, models were generated for the analysis of the behavior of stabilizers derived from Myrcene and Rubber Seed Oil (RSO). The models developed provide a basis for future research and practical applications in the improvement of thermal stability in PVC products involving bio-based stabilizers. It should be taken into account that in order to use these formulation tools correctly, the type of organic part and metal that form the stabilizing complex must be determined, since, depending on this, the values established in the model should vary. | spa |
