Rubber cure-metering, as we know it today, is a brainchild
of the late 1950s and the early 1960s.
During this
period of time, quite a number of different curemeters
were developed [1–6], some of which are still available
on the market. The curemeters took much of the earlier
guesswork out of the ‘rubber business’ since the instruments
provided information regarding: time to onset of
curing, curing speed, cure level, cure behavior (plateau
cure, marching modulus or reverting compounds) and
some indirect information on compound viscosity.
