Zinc oxide, stearic acid, tetramethylthiuram disulfide (TMTD), 4,4'-dithiodimorpholine (DTDM), and tetrabutylthiuram disulfide (TBTD
) were used.
A sinlilar evaluation of TBBS, TCS and TBTD
in SBR 1215 again showed TBBS to be most effective in terms of modulus and abrasion resistance.
Cure rates, as might be expected, were fastest for TMTM, ZBDC and TBTD
. However, none of these produced high levels of crosslinking.
No significant activity took place with zinc dimethyl dithiocarbamate (ZMDC), morpholino thio benzothiazole (MBS), tetrabutyl thiuran disulfide (TBTD
