Predicting the Cure State of Rubber Compounds
Predicting the Cure State of Rubber Compounds Rubber compounds are subjected to heat treatment with various methods and vul-canized for producing rubber based articles. During vulcanization, significant changes occur in physical properties of rubber com-pounds as it changes from a weak, viscoe-lastic material to a relatively strong viscoe-

Send InquiryA 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.
Send InquiryA 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.
Send InquiryHow 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

CURE CYCLE OPTIMIZATION. FIG. 1 shows a typical graph of torque (T) vs. time (t) for a particular compound cured at constant temperature and pressure. At t=0 for this given temperature the specimen has an initial stiffness or torque To. As t increases the stiffness or viscosity drops and the crosslink reaction begins.
