Abstract:

With the high temperature curing systems currently being used for the continuous vulcanization of rubber-covered wire, care should be exercised in selecting those accelerators most adaptable to the process. Investigation has shown that bismuth dimethyldithiocarbamate BISMATE and lead dimethyl dithiocarbamate LEDATE are of particular interest by virtue of their desirable temperature coefficients of vulcanization as measured from various stocks. These accelerators are apparently inactive until the higher continuous vulcanization temperatures are reached and then appear to function as stable compounds rather than dissociating into a complex system of free radicals. For the realistic evaluation of accelerators in CV compounds, equipment is required which will cure the stocks in open steam and at temperatures corresponding closely to those employed in the production equipment.
