Seeking Hollow Poly Balls


I am searching for hollow spherical balls of polypropylene, 5/8" or 3/4" in diameter. Color is unimportant, surface finish must be semi-smooth, with no sharp bumps or pits.

Look in plating supply catalogs for a product now available to retain heat and suppress fumes on plating baths. These are floating hollow spheres made of polypropylene, and come in sizes generally ranging from about 3/8 to 3 inches in diameter. The sizes you need should be available.

Just out of curiosity - what are these being used for?

Hi, Jeff. Canadian Finishing Systems can supply these (see letter 1316) as well as Saify Ind (see letter 3811).

Please note that such balls would be unpolished, so they might or might need meet your definition of semi-smooth. Good luck.

If you need a small quantity, you can get them from Amazon =>
