Rubber curemetering, 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. The
curemeters have long been an indispensable aid to the
rubber chemist as well for the production and the quality
control engineer.
