There are close relation between fluidity and processing of rubbers. The fluidity behaviors of rubber compounds can be explained by using the viscosity, pressure loss and stress relaxation factor as the processing index to realize the processability of rubbers in extruding and metal moulding cure processes. It can be considered that low viscosity, low pressure loss and proper stress relaxation factor should be necessary for extruding and metal moulding cure processes.
