AB  - Thermoplastic elastomer blends based on natural rubber (NR) and ethylene-vinyl 
      acetate copolymer (EVA) with different weight ratios (30, 40, 50, 60 and 70 parts 
      per hundred rubber (phr) of NR) and 10, 20 and 30 phr of straw were prepared and 
      characterized. Current environmental problems were the motivation to produce this 
      type of system, namely: the need to replace plastics at least partly with natural 
      materials; increasing the amount of renewable raw materials and managing excess 
      straw production. When using this bioadditive in traditional materials, the high 
      processing temperature can be problematic, leading to the degradation of straw 
      fibers. The solution can be polymer mixtures that are prepared at significantly 
      lower temperatures. Scanning electron microscope (SEM) imaging was used to 
      investigate the particle size of fibers and phase morphology of composites. 
      Moreover, determination of the thermal properties of the filler and composites 
      showed that the processing temperature used in the production of NR/EVA blends 
      reduces the risk of degradation of the natural filler. Differential scanning 
      calorimetry (DSC) was used to determine the thermal behavior of the filled 
      composites. Finally, rheological tests of materials allow the determination of 
      optimal processing parameters and properties of materials in dynamic conditions. 
      The proposed blends exhibit elastic properties, and due to the lack of chemical 
      cross-linking they can be processed and recycled like thermoplastics. In 
      addition, they offset the disadvantages and combine the advantages of natural 
      rubber and ethylene-vinyl acetate copolymer in the form of thermoplastic 
      elastomeric biocomposites.
