“…The first region is covered with low volatile content, such as processing oil or other elements of additives noticed in the composite upto 175°C due to the vaporization or decomposition of low boiling elements in the composites. 46 The next region occurred in the range of 176°C–550°C. The vaporization or degradation of the rubber phase was covered in the second region.…”

In this work, investigated the mechanical properties and microstructure of Ground Tyre Rubber (GTR) i.e. polymeric waste blended with Natural Rubber (NR), Butadiene Rubber (BR), and Styrene-Butadiene Rubber (SBR) composites. A two-roll mill and hydraulic press were used to create NR (70 parts per hundred of rubber (phr)) composites with 25 phr of BR and 5 phr of SBR and various proportions of GTR (0, 10, 20, 30, and 40 phr). With the incorporation of Nylon 6 (Ny 6) at 5 phr, the interfacial adhesion of NR/BR/SBR composites was improved. NR-based hybrid composites with mechanical and curing properties were enhanced and compared with pure NR. It was noted that the maximum tensile strength, tear strength, and hardness were enhanced by 77.74%, 17.9%, and 36.4% in NR/BR/SBR/GTR (70/25/5/40) over pure NR. The elongation at break was decreased by 54.55%, while young’s modulus was enhanced in NR/BR/SBR/GTR (70/25/5/40) over pure NR. With the incorporation of 40 phr of GTR in the NR/BR/SBR composites, cure properties like scorch time (tS2) and cure time (tC90) were reduced by 53.97% and 65.71%, while the minimum torque (ML) and maximum torque (MH) were enriched by 13.35% and 12%, respectively, when compared with the pure NR. Based on the Scanning Electron Microscope (SEM) and Thermogravimetric Analysis (TGA), GTR particles were uniformly distributed, and the thermal stability was enhanced by 25.40% in NR/BR/SBR/GTR (70/25/5/40) composites over pure NR. The absorption bands of NR, BR, SBR, and GTR elements in the developed hybrid composite were identified by Fourier transform infrared. The glass transition temperature (Tg) was diminished from -58.17°C to -63.42°C. With the inclusion of 40 phr of GTR in the NR/BR/SBR composite. Finally, it was recommended that the incorporation of 40 phr of GTR is suitable for NR/BR/SBR composites.

Antibacterial packaging represents an active packaging solution crafted to uphold the quality and safety of products. One of the popular polymer used in food packaging is Linear Low‐Density Polyethylene (LLDPE), due to its low cost, ease of processing, and high mechanical properties. Polymer blend based on LLDPE and antibacterial agent PHMG were prepared in the presence of PE‐g_AM compatibilizer and DCP initiator. The inclusion of PHMG resulted in a decline in the material's tensile strength. Specifically, in the sample containing 2% PHMG content, the tensile strength decreased by 11.6% in comparison to the original PE; whereas the elongation at break of the samples slightly increased. IR analysis confirmed the presence of characteristic groups of PHMG after the reaction. The polymer blend material acquired demonstrated antibacterial effects against both Gram‐negative (E. coli) and Gram‐positive (S. aureus) bacteria owing to the existence of PHMG within the material. The polymer blend sample LLDPE/2%PHMG/0.2%DCP/5%PE‐g_AM demonstrated the best antibacterial effect. The diameter of the S. aureus resistant zone reached 1.9 cm, 2.4 times bigger than the those of E. coli. The obtained properties of mechanical properties and antibacterial ability, polymer blend based on LLDPE/PHMG is suitable for application of antibacterial packaging film.
