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 [a finishing.com supporting advertiser] (see letter 3811).

Please note that such balls would be unpolished, so they might or might not meet your definition of semi-smooth. Good luck.

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