Influence of Viscosity Ratio on the Mechanical, Morphological, and Rheological Properties of Thermoplastic Dynamic Vulcanizates from Devulcanized Tire Rubber and Polypropylene

Macromolecular Materials and Engineering, EarlyView.
This study explores how polypropylene viscosity influences the structure and performance of thermoplastic dynamic vulcanizates made with devulcanized tire rubber. Higher matrix viscosity results in better dispersion of the rubber phase, forming smaller domains and enhancing mechanical properties. The findings support more efficient recycling strategies

Precision in Rubber Seal Lifetime Prediction: The Critical Role of Aspect Ratio

Polymer Engineering &Science, EarlyView.
This study examines how specimen geometry affects rubber seal aging predictions. We examine NBR and EPDM samples with varying aspect ratios (AR) under thermo‐oxidative conditions. Analysis includes indentation modulus, hardness, crosslink density, and calorimetric analyses. Results reveal how aspect ratio influences aging behavior.
