Dodgeball, also known as Playground ball, is a dynamic team sport. In this sport, players from two teams try to hit the members of the opposing team by throwing balls, while at the same time evading the balls thrown by the other side. The goal is to eliminate all members of the opposing team. Therefore, there are some special requirements for the material, performance and appearance of the balls used in dodgeball. Compared with rubber balls, the PVC softer dodgeballs we produce have very obvious advantages: they are softer, more elastic, non-toxic, no bad smell, and brightly colored. Moreover, our balls have a foaming effect on the surface, which increases the thickness of the ball shell without adding weight, making the balls more durable.
