“…The solubility parameter is an appropriate factor for evaluating the interaction between polymers and plasticizers. According to Hansen theory, solubility parameter (δ) is split into three Hansen solubility parameters (HSPs), including dispersion (δ d ), polar (δ p ), and hydrogen bonding (δ h ) parts, [ 21,50,51 ] (Equation [7]):

δ^{2} = δ_{d}^{2} + δ_{p}^{2} + δ_{h}^{2} .

“…The values of HSPs, and calculated R a and χ HSP for SBR and plasticizers are listed in Table 9. Since no clear data were available about all constituents of aromatic oil, its values of HSPs and molecular weight were estimated by average values based on Frashchi and Abbasian [ 50 ] and ASTM D2887, respectively. As seen, R a values for all canola oil constituents are the greatest, and the aromatic oil and D‐Limonene are in the next steps.…”

Substitution of petroleum-based processing oils with eco-friendly sustainable plasticizers in rubber compounds has gained much global attention due to their toxicity. In this regard, so far, the major attempts have focused on substituting aromatic oils with fatty acid based vegetable oils. In this work, the chemical and physical effects of canola oil as a model of fatty acid based vegetable oils on the process-ability, vulcanization kinetics, and final properties of carbon-black filled styrene-butadiene rubbers are systematically investigated. In contrast to the previous studies, it was shown that although these types of vegetable oils have a plasticizing impact, they can indeed threaten the requirements of reinforcing criteria in rubber vulcanizates. The final properties of the vulcanizates were found to be deteriorated due to the incompatibility of canola oil fatty acids constituents with rubber matrix and especially as a result of chemical interference of their unsaturated bonds in sulfur vulcanization kinetics.

“…When the aromatic oil exceeds 4 phr, the precipitation becomes basically unchanged. Toluene, xylene, and low-grade alkanes are the major constituents of environmentally beneficial aromatic oil, 44,45 and antioxidant N3100 is N-phenyl-N 0 -(2,6-dimethylphenyl) p-phenylenediamine. The similar chemical structure between the two components produced by the benzene ring leads to a strong interaction between their molecules or molecular chains.…”

Sidewall discoloration and fatigue directly affect the aesthetic value and functional efficiency of tires during their service life. This study designed L9 orthogonal experiments with oil, wax, and antioxidant as factors to study their effects on the discoloration and fatigue performance of tire sidewall rubber. Molecular dynamics simulation calculations, nonlinear finite element analysis, and modern characterization methods were adopted for the investigation. The findings indicated that antioxidant precipitation was the main cause of sidewall discoloration; aromatic oil accelerated sidewall discoloration and the expansion of tire sidewall fatigue cracks; and microcrystalline wax enhanced the fatigue properties of rubber compounds by halting the aging and breakdown of rubber molecular chains. This paper provides insights into the coordinated control and formulation optimization of tire sidewall material discoloration and fatigue life. Furthermore, it helps to reduce waste tires and sidewall chemical release into the environment.

“…Table 1 shows the solubility parameter of commonly used oils of mineral origin and selected vegetable origin and few elastomers. [1][2][3][4][5] Commercially available OE-SBR's are extended with aromatic oil which contains about 70-85 weight percent total aromatics and 10-15 weight percent PAHs (Polyaromatic hydrocarbons)/PCAs (Polycyclic aromatics). These oils show good compatibility with SBR, however, they are toxic and carcinogenic due to high PCA content.…”

Currently emulsion polymerized Styrene Butadiene Rubber (E-SBR) is extended with various petroleum based mineral oils like Distillate Aromatic Extract (DAE), Treated Distillate Aromatic Extract (TDAE), Residual Aromatic Extract (RAE) and Naphthenic oils. It is obvious that introduction of vegetable oil should result in almost zero Polycyclic Aromatic Content (PCA) content and therefore, are environmentally friendly, renewable, and sustainable. In the present work, vegetable oil extended Styrene Butadiene Rubber (OE-SBR) were characterized for chemical properties and found that all the properties were meeting the specification requirements of mineral oils extended grades. These rubbers were also evaluated in standard Passenger Car Radial (PCR) tire tread compound recipe for various processing, different vulcanizate and other performance properties. The developed grades with vegetable oils required less mixing energy (around 10% for master batch and 15% for final batch) and shown better flow behavior (around 15% power law index and 20% activation energy reduction), better carbon dispersion (around 20%), high reinforcement index (around 15%), better rubber-filler interaction parameter (around 20%), better abrasion resistance (around 20%) and lower tanδ value @60°C (around 15%) as compared to TDAE oil extended SBR based compound. This may help to improve life of a PCR tire and reduction in fuel consumption of the vehicle.
