Problems solved by technology

[0002] Due to its special purpose, sports shoes require its sole rubber to have anti-slip performance and good cold resistance. However, the rubber used in the current sports shoe soles is mainly formulated with isobutylene-isoprene containing active bromine. Mainly copolymer elastomer, this kind of rubber sole is very unstable in the production process. Although the sole rubber has good performance in anti-slip performance, it has certain deficiencies in elasticity and anti-slip performance under cold conditions; The soles of sports shoes are easy to slip during bouncing and running in cold conditions, and the soles wear out quickly and lose their elasticity
