On the other hand, if the temperature is too low, the decrease in rubber viscosity is low. It is also possible to adopt a method in which the rubber temperature is raised by shearing heat generation. However, in this method, it is preferable to set the temperature as described above in order to exert stable productivity in an extruder.
