[0002] Closed rubber mixer is also called internal mixer, which is mainly used for rubber plasticizing and mixing. Internal mixer is a machine with a pair of relatively rotating rotors of specific shapes, which plasticizes and mixes polymer materials intermittently under a closed state with adjustable temperature and pressure.

[0003] Due to the promulgation of tire labeling laws and consumers' increasing demand for tire fuel performance, tire rolling resistance has become the top priority among all performance factors. Tread rubber is the rubber compound that has the greatest impact on tire rolling resistance.
