Description

3M™ Glass Bubbles are engineered hollow glass microspheres that are alternatives to conventional fillers and additives such as silicas, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties. The unique spherical shape of 3M glass bubbles offers a number of important benefits, including higher filler loading, lower viscosity/improved flow and reduced shrinkage and warpage. It also helps the 3M glass bubbles blend readily into compounds and makes them adaptable to a variety of production processes including spraying, casting and molding.

Features

Hollow glass microspheres are ideal for a number of applications including shallow (up to 2000 ft of sea water) water flotation devices and lightweight wall repair compound
Low cost, economical bubbles have a very low typical density (0.125 g/cc) and an isostatic crush strength of 250 psi
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
Stable voids for low thermal conductivity and reduced dielectric constant
Versatile use - adaptable to a variety of production processes
Provides buoyancy in syntactic foam compositions
Additive can easily be sanded in lightweight wall repair compounds
Chemical and temperature resistance
For bowling balls, cast polyester, paints and coatings, drill riser buoyancy modules, caulk, adhesives, emulsion explosives, polyester putty, potting compounds, tooling boards and spackling compound applications
60 to 69 particle size range (D50 micron)
1.7 Mpa strength
>=600 deg C softening point
