1. Different materials, rubber and silicone are both materials modified from natural rubber by adding chemical additives. Due to the different compositions and proportions of various chemical additives, there are dozens of models and specifications in rubber balls. Plastic balls, on the other hand, use polymer synthetic resins as the main raw material and are manufactured with different material models by adding different chemical additives.

2. Different uses: Rubber balls have the characteristics of good wear resistance, strong elasticity, high and low temperature resistance, oil and chemical resistance, and are widely used in fields such as automobiles, machinery, and chemical industry. Rubber balls generally have better elasticity than plastic balls. The characteristics of plastic balls are high hardness, wide range of materials, and different types of plastic materials can be used to produce plastic balls according to different needs. Plastic balls have the characteristics of high precision, good self-lubricating performance, high precision, and long service life, and are widely used in fields such as automotive parts, mechanical manufacturing, electronics, medical, aerospace, etc.
