3M™ Glass Bubbles H50/10000 are hollow glass microspheres with a typical density of 0.50 g/cc and an isostatic crush strength of 10,000 psi. These glass bubbles are designed for buoyancy and insulation in ultra-deep water applications for oil and gas drilling and coatings for subsea equipment. The bubbles produce strong, stable voids helping coatings achieve the necessary compressive strength.
3M™ Glass Bubbles H50/10000 EPX have a density of 0.50 g/ cm3 and an isostatic crish strength of 6000 psi / 414 bar.They have epoxy silane surface treatment. They are part of Floated product Series and hae less than 1% sinkers by volume. They offer the same combination of strength and light weight as standard 3M Glass Bubbles with an added surface treatment of special coupling agents, for use in high tech applications such as aerospace and hydrospace syntactic foam, radomes and printed wire boards
