Prediction of Cure Level in Thick Rubber Cylinder Using

was used to predict cure distribution of thick rubber cylinder. THE CURING PROCESS Due to low thermal conductivity of rubber compounds, their cure by the application of heat never occurs under steady state thermal conditions. On the contrary, transient conditions prevail throughout the whole of the curing cycle. Moreover,

A Prediction Model for Rubber Curing Process

dimensions, low thermal conductivity of the rubber leads to non-uniform distributions of the temperature history, which results in non- uniform cure state in the rubber. Since rubber curing process is an exothermic reaction, both heat conduction equation and expressions for the curing kinetics must be solved simultaneously.

A new approach to optimize cure cycle of a tire using DSC

A new approach to optimize cure cycle of a tire using DSC. This corresponds to about 90% achievement of state of cure. By comparing these two findings (physical properties and DSC results), technically one can predict how much time is to be provided in the process of curing in order to get a quality product.

How to reduce the cure time without damaging the rubber

In the rubber injection process, the compound has a thermal history that starts from room temperature when the rubber strip enters the extruder and reaches up to the finished part when it is cooled down to room temperature. In few cases, a post-cure process is done by putting the part in an oven for a certain period of time. This is a
