Hollow spheres

Listing ID #4586940

Hollow Spheres are only a fraction of the density of commonly used resins. It only takes a small addition by weight of Hollow Spheres to displace heavier materials. They simultaneously add volume and reduce density. If you are looking for buoyancy, no filler performs as well as Potters Hollow Spheres. Additionally, they can save material costs; on a volume basis, microspheres are a fraction of the cost of resins.
