About Plastic and Rubber Balls
Plastic and rubber balls are sphere shapes that are used as check or ball valves, bearings, and in other applications. They are made of elastomers, thermoplastics, thermoset plastics, or composite materials. Elastomers and rubber materials are characterized by their high degree of flexibility and elasticity (high reversible elongation). Thermoplastics can be repeatedly softened by heat and then hardened, or set by cooling, which allows parts to be injection-molded or thermoformed and scrap to be reprocessed. Thermoset plastics and thermoset resins are cross-linked polymeric resins that are cured using heat or heat and pressure. Plastic and rubber balls that contain composite materials are filled with a strengthening phase, reinforcement fibers, toughening phase, or other specialty fillers that provide unique properties.
