Hollow Glass Ball

Hollow Glass Balls used in composite (SMC-BMC-RTM), paint coating, varnish, artificial marble and repair putties have a grain size between 30 and 120 microns. Balls with a compressive strength between 3.5 Mpa and 124Mpa have a specific gravity of 0.18gr/cm³ to 0.58gr/m³. This filling material, which provides a great advantage in terms of volume, provides superior performance in the final product.
