Hollow glass microspheres made from water-resistant and chemically-stable soda-lime borosilicate glass. Like all hollow glass microspheres, our H50/10000 bubbles are virtually insoluble in water or oil, making them suitable for use in a number of underwater applications. Additionally, they are non-combustible, low alkaline and non-porous, so they do not absorb resin; and hollow glass microspheres are compatible with most resins.
These low-density hollow glass microspheres are used for many demanding applications across a wide range of industries to provide temperature and pressure resistance and reduce part weight. For these reasons, hollow glass microspheres are a superior alternative to many conventional fillers and additives such as silica, calcium carbonate, talc and clay.
