The material used in EVA sports sole is ethylene / vinyl acetate copolymer, which is prepared by the copolymerization of ethylene (E) and vinyl acetate (VA), referred to as EVA. Compared with polyethylene, EVA introduces vinyl acetate monomer into the molecular chain, which reduces the high crystallinity and improves the flexibility, impact resistance, miscibility of fillers and thermal sealing performance. EVA sole has good resilience and tension resistance, high toughness, good shockproof and cushioning performance.
