3M™ Glass Bubbles G18/500 are non-surface treated bubbles that are part of our Floated Product Series. These hollow glass microspheres have a crush strength of 500 psi and a true density of 0.18 g/cc – making them a strong, yet lightweight additive used in a number of applications, including aerospace, deep water syntactic foams and sporting goods.
- Decreases weight and increases buoyancy to improve efficiency and may lower material costs
- Provides excellent water and oil resistance for use in underwater applications
- Reduction in overall pipe diameter results in more pipe on reels used for reel-lay pipe installation operations
- Provides temperature and pressure resistance for versatile use – adaptable to a variety of production processes
