“…This effect is due to the introduction of norbornyl groups to the SO. Similar effect was also observed in the sulfur‐cured EPDM and SBR vulcanizates. After decreasing the oil level to 10 phr, various IIR vulcanizates exhibit a slightly increased T g , but still in the same order with respect of various oils.…”

“…It is an excellent alternative oil resource for the rubber industry. Previous studies investigated the replacement of petroleum‐based plasticizers by SO in styrene‐butadiene rubber (SBR), natural rubber (NR), polychloroprene rubber (CR), ethylene‐propylene‐diene rubber (EPDM), and rubber blends . It was found that SO could be a replacement of petroleum‐based rubber plasticizers in various rubber compounds, but with some deficiency in certain properties.…”

Butyl rubber (also known as isobutylene isoprene rubber, IIR) containing plasticizers and cured by phenolic resin is widely used to manufacture rubber products exposed to high temperature environments. Therefore, carbon black (CB)‐filled IIR containing a petroleum‐based plasticizer [naphthenic oil (NO)] and environmentally friendly bio‐based plasticizers [soybean oil (SO) and norbornylized soybean oil (NSO)] cured by the brominated phenolic resin were studied. The NSO was prepared through the reaction of SO and dicyclopentadiene at different ratios. Gel fraction, crosslink density, curing behavior, thermal, mechanical, and aging properties of the CB‐filled IIR containing different oils were investigated. The addition of SO and NSO increased the thermal stability and decreased the crosslink density of the IIR vulcanizates compared to that of the IIR/NO vulcanizate. This was found to be due to the reaction between the phenolic resin and the bio‐based oils. Reducing the oil level increased the crosslink density of the IIR/SO and IIR/NSO vulcanizates, which in turn increased the modulus and tensile strength. Among various vulcanizates, the IIR/NSO vulcanizates showed the best overall hot air aging resistance. Results showed that NSO in the amount less than 10 phr could be a good replacement for the petroleum‐based plasticizer in IIR cured by phenolic resins. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…It is already confirmed that TSO is an excellent plasticizer for EPDM from our previous work 10 ; however, it was also found that the introduction of TSO reduced the crosslinking density because the double bonds of TSO could react with the crosslinker. Petrović synthesized polymerized soybean oil by cationic method and successfully reduced the influence of soybean oil on crosslinking density . In this study, three HTSOs with different degrees of hydrogenation were prepared by hydrogenation of TSO to reduce the amounts of double bonds.…”

Plasticization effect of hydrogenated transgenic soybean oil on nitrile‐butadiene rubber

Nitrile‐butadiene rubber (NBR) compounds were prepared with different amounts of hydrogenated transgenic soybean oil (HTSO) as renewable plasticizers. For comparison, similar compounds were prepared with petroleum‐based dioctyl‐phthalate (DOP), one of the most common plasticizers for NBR. Four HTSOs with different degree of hydrogenation were used, of which three HTSOs are prepared by hydrogenation reaction at different reaction conditions and one is commercial available. The plasticization effects of HTSO and of DOP were studied by Mooney viscometry, capillary rheometry, differential scanning calorimetry (DSC), and rubber processing analysis (RPA). The results showed that all the HTSOs had better plasticization effect than DOP on NBR. The swelling index result showed that the highly‐hydrogenated‐HTSO plasticized NBR vulcanizate have higher crosslinking density than the low‐hydrogenated ones. It is worthy to mention that, the introduction of high‐hydrogenated‐HTSO greatly improved both the processability of the NBR compounds and the mechanical performance of the final products, which is hard to achieve for most of the plasticizers. © 2014 Wiley Periodicals, Inc.

“…In Ref. [8] it is reported that soybean oil could be substituted for conventional oil in natural and styrene butadiene rubbers with minimal differences in mechanical and dynamic properties. The effects of replacing a portion of petroleum oil with soy-based oils on the cure kinetics and mechanical properties of EPDM (ethylene propylene diene monomer) rubbers have been investigated in Ref.…”
