Rubber-coated ball is a ball made by covering a layer of rubber coating on the surface of a substrate such as metal, plastic or glass. The coating can be natural rubber, nitrile rubber, silica gel and other rubber materials, giving the ball good anti-slip, wear resistance, buffer performance and protection ability. Rubber-coated balls are often used in application scenarios that require high shock absorption, grip and protection.
