For organic peroxide vulcanization, a variety of organic peroxides have been shown to be effective [7]. Such peroxides would include di-t-butyl peroxide dicumyl peroxide t-butyl cumyl peroxide l,l-di(t-butylperoxy)-3,3,5-trimeihyl cyclohexane 2,5-dimethyl-2,5-di(r-butylperoxy)hexane 2,5-dimethyl-2,5-di(r-butylper-oxy)hexyne-3 a,a-bis(t-butylperoxy)diisopropylbenzene t-butyl perbenzoate and t-butylperoxy isopropylcarbonate. In contrast to NBR elastomers where 1-3 phr of peroxide is effective, HNBRs generally require peroxide levels of 5-8 phr for effective vulcanization. As discussed earher, this is due to the very low levels of unsaturation present in the HNBR polymers. The specific peroxide chosen will depend on the process safety desired and the vulcanization temperature to be used. Generally, the most common organic peroxides used in HNBR elastomers are Dicumyl peroxide, such as Varox Dicup 40C from R.T. Vanderbilt, on an inert carrier for vulcanization below 177°C and a,a-bis(t-butylperoxy)diisopropylbenzene, such as Varox VC40KE from Vanderbilt, on an inert carrier for vulcanization above 150°C.
