Abbott can supply plastic balls in Acetal, CelconŽ and DelrinŽ and Polypropylene. Plastic balls can be used as a substitute in low load bearings, agitators in aerosol spray cans, and in lightweight check valves. Plastic is lower in cost and used where weight is not an issue. Plastic balls are available in a range of sizes, tolerances, and grades of plastic.
