SPHERES DESIGNED FOR USE IN A VARIETY OF OIL AND GAS APPLICATIONS
3M™ Glass Bubbles S15 are hollow glass spheres with a density of 0.15 g/cc and an isostatic crush strength of 300 psi. These glass bubbles are designed for a number of industries, including auto body repair fillers and syntactic foams for deep water buoyancy. The bubbles produce strong, stable voids and low thermal conductivity, helping the coating achieve the necessary compressive strength.
