Synergistic effects of antioxidant and silica on enhancing
Among natural rubber (NR), butadiene rubber (BR), styrene butadiene rubber (SBR), and other diene rubbers, NR has been broadly applied in a variety of industrial commodities, such as engineering tires, shock absorber, footwear, latex products, given its excellent comprehensive performance.

Some Synergistic Effects of Antioxidants in Natural Rubber
Abstract. Some synergistic effects of antioxidants in natural rubber were investigated considering results obtained by differencial scanning calorimetry (DSC). Rubber formulations were obtained with mixtures of diaminic (DPPD, IPPD, HPPD) and monoaminic (ADPA, PBN) stabilizers and evaluated. The samples containing the mixture diamine/ADPA stabilizers...

Synergistic antioxidant combination - R. T. VANDERBILT
The antioxidant combination of the invention can be added to natural rubber or the like in an amount ranging from about 0.25 to 5 parts per hundred parts of rubber (phr). The synergistic combination can be employed with a rubber latex, a rubber solution, and a solid rubber to retard the oxidative deterioration of the rubbery polymer during polymerization.

antioxidantsand antiozonants
polymers that have antioxidants added to their latex phase of processing to protect them from oxidation. Natural rubber polymers normally do not need the addition of “polymer sta bilizers” to be protected against oxidation. Natural rubber already contains naturally occurring antioxidants that protect the polymer from oxidation.

Synergistic antioxidant combination of organic phosphite
The antioxidant combination of the invention can be added to natural rubber or the like in an amount ranging from about 0.25 to 5 parts per hundred parts of rubber (phr). The synergistic combination can be employed with a rubber latex, a rubber solution, and a solid rubber to retard the oxidative deterioration of the rubbery polymer during polymerization.

Rubber compounding ingredients - Rubber compounds
Rubber compounding ingredients. A synergistic effect when a combination of two antioxidants is more effective than any of them in the same concentration as observed in different mechanisms of action. There is a synergistic effect of substituted phenols and amines with phosphorous acid esters, amines with sulfides.

Investigation of Sulfur Crosslinking Interfacial
The sulfur crosslinking films from Natural Rubber (NR), Carboxylated Stryrene Butadiene Rubber (XSBR) latices, and their blends have been investigated using X-ray absorption near-edge structure spectroscopy (XANES). The film was prepared by casting the latex compound on glass surface and heating at 120oC in a hot air oven for 10 minutes. The sulfur crosslinking density were studied by the XANES.

VANOX® ZMTI Antioxidant and VANOX MTI Synergistic Antioxidants maximize a product’s resistance to high temperature. Rubber compounds are usually protected by just one antioxidant, but more severe service conditions require combinations of antioxidants. VANOX ZMTI is an antioxidant that is manufactured at Vanderbilt Chemicals, LLC plant in Murray, KY.
