Optimum Cure Time Rubber

As previously stated the cure time is determined from the rubber in the center of the flow whereas the limit is.
Optimum cure time rubber. Is the optimum curing time tc90 at rheometer. Therefore precisely defining the curing process including optimum cure time is important to ensure the production of final products having high performance. However according to the author s knowledge no comprehensive work was dedicated to monitor and predict optimum cure time of rubber compounds. Only few cavities will dictate the cure time.
A new method to predict optimum cure time of rubber compound using dynamic mechanical analysis article khimi2014anm title a new method to predict optimum cure time of rubber compound using dynamic mechanical analysis author s. The degree of vulcanization of a rubber compound has a big influence on the properties of the final product. Pickering journal journal of applied polymer science year 2014 volume 131. Optimum cure time t90 is the time required for the torque to reach 90 of the maximum achievable torque tc90 and relates to the time which is necessary for the cured rubber to achieve optimal.
Cure time whereas the high compound temperature cavity will determine the injection pressure and mold temperature limit. If the time is short to heat it up it may require a longer cure time and if the unit requires a long time to heat it may require a shorter cure time. Length of time to get up to cure temperature. As same the curing time when vulcanized higher weight samples by using a hot press used for testing the mechanical properties of rubber compounds.
Length of time to cool down with rubber lined equipment left in autoclave will also have an influence on the cured lining hardness. Raa khimi and keith a. Typically vulcanization is represented using vulcanization curves. Rubber compounds that have different formulations differ also in curing behaviors.
In this work the dma is tested for suitability for monitoring cure of rubber compounds. The low compound temperature cavities.
