TL;DR: In this paper, a process for making a carbon-filled rubber having a uniform dispersion of nanometric-sized carbon black particles is provided, which provides a black masterbatch rubber with superior mechanical and rheological properties.
Abstract: A process is provided for making a carbon-filled rubber having a uniform dispersion of nanometric-sized carbon black particles. Fluffy carbon black is received as a slurry in water and added to latex rubber before or during coagulation in an emulsion styrene butadiene rubber plant, or fluffy carbon black is similarly incorporated in rubber using a different type of rubber-manufacturing process. A uniform dispersion of smaller-than-usual carbon black particles in rubber is formed, which provides a black masterbatch rubber with superior mechanical and rheological properties. Ash and grit is removed from the fluffy carbon black slurry, which further improves the properties of the carbon-filled rubber by reducing defects in the rubber caused by the ash or grit.

TL;DR: In this article, the brake parts and the power transmission belt based on the ethylene, alpha-olefin, vinyl norbornene elastomeric polymer have improved resistance to elevated temperature properties, and good heat aging characteristics, compared to for instance polychloroprene, or styrene butadiene rubbers.
Abstract: Motor vehicle brake parts and power transmission belt based on an ethylene, alpha-olefin, vinyl norbornene elastomeric polymer are manufactured with more efficiency due to brake part compounds having lower viscosity, faster and fuller cures than ethylene, alpha-olefins, diene monomer compounds, where the diene monomer is other than vinyl norbornene. Additionally, the brake parts and the power transmission belt based on the ethylene, alpha-olefin, vinyl norbornene elastomeric polymer have improved resistance to elevated temperature properties, and good heat aging characteristics, compared to for instance ethylene, alpha-olefin, non-conjugated diene elastomers (where the diene is other than vinyl norbornene) polychloroprene, or styrene butadiene rubbers.

TL;DR: In this paper, the immobile antioxidant intermediate 4-aminodiphenylamine (GO-RT) was used as a filler to prepare styrene-butadiene rubber (SBR) composites for enhancing the thermal oxidative stability.
Abstract: In this work, graphene oxide (GO) was functionalized with the reactive antioxidant intermediate 4-aminodiphenylamine (RT) to obtain the immobile antioxidant (GO-RT). Then the GO-RT was used as a filler to prepare styrene-butadiene rubber (SBR) composites for enhancing the thermal oxidative stability. The results of fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray spectrometry (EDS), X-ray diffraction (XRD) and Raman spectroscopy demonstrated that RT has been successfully grafted onto the GO. The grafting efficiency of GO-RT was evaluated by thermogravimetric analysis (TGA). Oxidation induction time (OIT) tests, electron paramagnetic resonance (EPR) and accelerated aging tests revealed that GO-RT presented much better anti-oxidative and anti-migratory efficiencies than the corresponding low molecular counterpart (4010NA). Additionally, the mechanical strength of the modified rubber composites was also improved by the GO-RT. Thus, the GO-RT antioxidant has the excellent ability to improve the thermal oxidation resistance of SBR and also could obviously strengthen SBR.

TL;DR: The application of organic zinc activators allows the amount of zinc ions in SBR compounds to be reduced by 70–90 wt % compared to vulcanizate with zinc oxide, which is very important for ecological reasons, since zinc oxide is classified as being toxic to aquatic species.
Abstract: Organic zinc salts and complexes were applied as activators for sulfur vulcanization of styrene-butadiene elastomer (SBR) in order to reduce the content of zinc ions in rubber compounds as compared with conventionally used zinc oxide. In this article, the effects of different organic zinc activators on the curing characteristics, crosslink densities, and mechanical properties of SBR as well as the aging resistance and thermal behavior of vulcanizates are discussed. Organic zinc salts seem to be good substitutes for zinc oxide as activators for sulfur vulcanization of SBR rubber, without detrimental effects to the vulcanization time and temperature. Moreover, vulcanizates containing organic zinc salts exhibit higher tensile strength and better damping properties than vulcanizate crosslinked with zinc oxide. The application of organic zinc activators allows the amount of zinc ions in SBR compounds to be reduced by 70-90 wt % compared to vulcanizate with zinc oxide. This is very important for ecological reasons, since zinc oxide is classified as being toxic to aquatic species.
