This difference is more evident in the compounds with fillers usually carbon black due to matrix filler interactions.
Optimum cure time rubber.
Pickering journal journal of applied polymer science year 2014 volume 131.
The degree of vulcanization of a rubber compound has a big influence on the properties of the final product.
However according to the author s knowledge no comprehensive work was dedicated to monitor and predict optimum cure time of rubber compounds.
Typically vulcanization is represented using vulcanization curves.
Raa khimi and keith a.
Only few cavities will dictate the cure time.
Cure development and important transitions in cure process such as gelation and vitrification point 10 13.
Cure time whereas the high compound temperature cavity will determine the injection pressure and mold temperature limit.
Length of time to cool down with rubber lined equipment left in autoclave will also have an influence on the cured lining hardness.
In this work the dma is tested for suitability for monitoring cure of rubber compounds.
Rubber compounds that have different formulations differ also in curing behaviors.
As same the curing time when vulcanized higher weight samples by using a hot press used for testing the mechanical properties of rubber compounds.
Therefore precisely defining the curing process including optimum cure time is important to ensure the production of final products having high performance.
In rubber terminology t90 is defined as optimum cure time for the rubber compound studied.
Is the optimum curing time tc90 at rheometer.
The low compound temperature cavities.
