摘要： Embodiments of organic peroxide formulations provide longer scorch time protection and require fewer additives. The peroxide formulations may include, for example, at least one organic peroxide, at least one nitroxide-containing compound (e.g., 4-hydroxy-TEMPO), and at least one quinone-containing compound (e.g., mono-tert-butylhydroquinone).

摘要： Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).

摘要： An organic peroxide formulation comprises at least one organic peroxide, at least one drying oil, and at least one free radical trap. A process comprises curing mixtures that include at least one elastomer and the organic peroxide formulation in the presence of oxygen. Elastomer compositions, methods of manufacturing elastomer articles, and elastomer articles made from the elastomer compositions are also disclosed.

摘要： An organic peroxide formulation includes at least one organic peroxide and at least one cellulose compound. Embodiments of the organic peroxide formulations significant improvements in surface tackiness (often including but not limited to tack-free surfaces) when curing elastomers in the presence of oxygen. Embodiments of the present invention relate to organic peroxide formulations that can cure solid elastomers in the full or partial presence of oxygen using, for example, a hot air oven or tunnel, molten salt bath, or steam autoclave. Embodiments of the invention also relate to crosslinkable elastomer compositions, processes for curing the elastomers, and products made by such processes.

摘要： A peroxide formulation includes at least one peroxide and at least one compound having a secondary amine group selected from amino acids, such as arginine, folic acid, and polyethyleneamines. The peroxide formulation is capable of curing an aqueous elastomer such as a latex in the full or partial presence of oxygen. Methods of using the peroxide formulation include dip-molding latex elastomer compositions.
