Facts

• Materials used to make rubber balls include composite materials, elastomers, thermoplastics and thermoset plastics. Rubber materials such as elastomers have better flexibility than other materials. Thermoplastics allow for injection molding, while composites provide reinforcement for special uses, according to the website Global Spec.
  
  

Features

• Chemical systems also play a role in the manufacturing of rubber balls. For example, epoxy balls are tougher, fluoropolymers have better chemical resistance and thermoplastics are stronger, with higher temperature resistance.
  
  

Uses

• The automotive, tooling, construction, medical and marine industries use rubber or plastic balls. Usage is based on size, composition and temperature, because rubber balls eventually break down.
