“…Therefore, there is still a need to develop new TPVs. [5][6][7] EPDM has excellent aging resistance (ozone resistance, heat resistance and weather resistance) and good compatibility with PP, 8,9 but also has poor adhesion and a relatively high price. 10,11 High vinyl polybutadiene rubber (HVPB) has good thermo-oxidative aging resistance, good damping performance at room temperature 12,13 as well as good compatibility with PP.…”

Thermoplastic vulcanizates (TPV) composed of high vinyl polybutadiene rubber (HVPB) and polypropylene (PP) have good thermal stability and damping properties. This work aims to apply a design of experiments (Taguchi L9 orthogonal array) to optimize the mixing parameters (rotor speed, temperature, and time) for the HVPB/PP TPV. The effects of these mixing parameters on its physical and mechanical properties of HVPB/PP TPV follow the order: rotor speed > temperature and time. In the case of the master batch process, the optimum mixing parameters are 60 rpm, 180°C and 8 min. Subsequently, four processes (master batch, static vulcanization, rubber‐plastic premixing, and two‐step processing) are compared using the same optimum mixing parameters. The master batch process turns out to be the best in terms of physical and mechanical properties.

“…6,7 For instance, TPVs can be used to fabricate heart valve implants that mimic the heart's movement. 8 Additionally, TPVs are suitable for medical devices like catheters, tubing, and syringes, which require both exibility and durability. 9 This study developed a novel non-petroleum-based options to address the need for sustainable alternatives to petroleum-based TPVs.…”

We successfully prepared butyl rubber (IIR)/polypropylene (PP) thermoplastic vulcanizate (IIR/PP-TPV) for shock-absorption devices by dynamic vulcanization (DV) using octyl-phenolic resin as a vulcanizing agent and studied the morphological evolution and properties during DV. We found that the damping temperature region of the IIR/PP-TPV broadened with the disappearance of the glass transition temperature (Tg) in the PP phase, which is ascribed to the improvement of compatibility between the IIR and PP with increasing DV time. As DV progresses, the size of the dispersed IIR particles and the PP crystalline phase decreases, leading to the formation of a sea–island morphology. After four cycles of recycling, the retention rates of tensile strength and elongation at break of the IIR/PP-TPV reached 88% and 86%, respectively. The size of the IIR-cross-linking particles in the IIR/PP-TPV becomes larger after melt recombination, and the continuous PP phase provides excellent recyclability. Significantly, the prepared IIR/PP-TPV exhibits excellent recyclability, high elasticity, and good damping property.
