Gelling I. R., . and Metherell C., . Vulcanisation systems for ENR-50. pp. 37-56. ISSN 0127-7065
Abstract
This paper compares the effects of cure systems on the physical properties of ENR-50. Semi-EV EV sulphurless and some of the newer formulations such as equilibrium cures and post-vulcanisation stabiliser systems have been studied. There is considerable interest currently in vulcanisation systems which do not give rise to volatile nitrosamines and consideration is given to this aspect of selection of vulcanisation systems. The adjustment of formulations for high temperature curing and injection moulding is also demonstrated. It is shown that ENR-50 may be successfully injection moulded at 180 C and with carefully designed cure systems compression set similar to that obtained by compression moulding at 150C can be achieved.
