A look at cure, aging of hose compounds

The state-of-cure and property changes of an EPDM hose compound were studied as a function of cure and aging history. Time domain (TD) NMR was used for tracking changes to the state of cure. Mini DeMattia was used to characterize the
changes in cut growth resistance.
Mini DeMattia is particularly useful when only small samples can be extracted from a molded rubber component. These techniques were applied to an EPDM hose compound. The property changes as a function of cure and aging (air-oven) of the EPDM hose compound were quantified...
