    Influence of plantation climate and storage time on thermal and viscoelastic properties of natural rubber by Allen Jonathan Román, Jamelah Zena Travis, Juan Carlos Martínez Ávila, Tim A. Osswald

    Published 2021-03-01
    “…The unvulcanized NR was used to conduct a preliminary study, part of a long-term study, to uncover some underlying mechanisms in charge of imparting variation between NR batches, such as the collection site's rainfall conditions and storage period by using calorimetry, rheometry, and a dynamic mechanical analyzer. The ultrasound study found that an increase in monthly rainfall increased the material's elastic constant at 10 MHz, and the crystallization study uncovered that the amount of crystallization decreased with increased rain while remaining relatively constant if rainfall was within the recommended rainfall amount for the tree. …”
