DI-CUP® R
Curing agent for rubber and elastomer crosslinking applications.
#CAS 80-43-3
Product overview
Di-Cup® R crystal is a curing agent for rubber and elastomer crosslinking applications. When heated, it forms alkoxy radicals that abstract hydrogen from a polymer backbone, forming polymer radicals. A combination of two radicals results in a crosslink. In general, the crosslinking rate is equivalent to the rate of Di-Cup® R dicumyl peroxide decomposition. The rate of cure is therefore dependent on cure temperature and can be predicted for each polymer system. Typical processing temperature for compounds containing Di-Cup® R is 300°F to 425°F.
