Nitrosamine safe accelerators for dry rubber compounds 106 accelerators have been identified as generating secondary amine intermediates during vulcanization (Goss et al., 2006). They are dithiocarbamates, sulfenamides, sulfur donors and thiurams (Goss et al., 2006). Most of the accelerators used in the
Development and application of an LC-MS method to
A method was developed for the analysis of food and drink for residues of specific vulcanization accelerators used to cross-link rubber. The method was applied to the analysis of 236 samples of selected retail foodstuffs that may have been in contact with rubber during their manufacture, transport and storage.
Rubber products, comprising natural (rubber latex) or synthetic elastomers, are widely used in everyday and working life. Rubber additives, either as remnants from the production process (such as accelerators) or those deliberately added to enhance the product characteristics (such as antioxidants), constitute an important group of contact allergens.

Mar 01, 2013· This article explores the abilities of two commonly used features of Alpha Technologies' RPA2000, PPA2000 and/or the MDR2000 to detect potential problems and guide the rubber compounder to the proper corrective action. It was also observed that adjustments in stearic acid and CBS accelerator did increase the [E.sub.a]. Norfolk, U.K
Aug 02, 2019· One of the main applications of ZnO relies on the rubber industry as chemical activator of the vulcanization process. In fact, more than 50% of the ZnO global annual production (25 million tons reported in 2010 ) is used in rubber manufacturing [17,18,19] with tires production comprising its primary destination [20,21].
