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.
- Decreases density and increases buoyancy to help improve efficiency and may lower material costs
- Provides excellent water and oil resistance for use in underwater applications
- Decreases thermal conductivity in syntactic foam compositions
- Very good strength-to-density ratio
