The invention discloses a rubber composition, vulcanized rubber and application of vulcanized rubber. The rubber composition contains dialkene rubber, white carbon black, a hollow microbead filler and a coupling agent. Specifically, the hollow microbead filler is hollow glass microbeads, and has body density of 2.0-3.0g/cm<3> and bulk density of 1.0-1.8g/cm<3>. The hollow microbead filler contains 55-65wt% of SiO2 and 15-25wt% of Al2O3, and has an average particle size of 2-10 micrometers. The mineral phase of the hollow microbead filler is an amorphous vitreous body. The rubber composition can effectively improve the dispersion of white carbon black in a rubber matrix, and reduces the aggregation of white carbon black filler particles, so that mixed rubber can have good processing performance, the energy consumption of mixing is low, and the dynamic mechanical properties of the vulcanized rubber are also good.
