Product Benefits
  • The spherical shape of 3M™ Glass Bubbles Types H20/1000 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 Types H20/1000 blend readily into compounds, and makes them adaptable to a variety of production processes, including spraying, casting and molding. In addition, they offer greater survivability under demanding processing conditions, such as injection molding, and also produce stable voids, which results in low thermal conductivity and a low dielectric constant.
  • The chemically stable soda-lime-borosilicate glass composition of 3M™ Glass Bubbles Types H20/1000 provides excellent water resistance, to create more stable emulsions. They are also non-combustible and non-porous, so they do not absorb resin. And, their low alkalinity gives 3M™glass bubbles compatibility with most resins, stable viscosity and long shelf life.
  • 3M™ Glass Bubbles Types H20/1000 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. They are available in a variety of sizes and grades for various product and processing requirements.

Storage & Handling

Storage Conditions

3M™ Glass Bubbles have been made from a chemically stable glass and are packaged in a heavy duty polyethylene bag within a cardboard container. Minimum storage conditions should be unopened cartons in an unheated warehouse.

Under high humidity conditions with the ambient temperature cycling over a wide range, moisture can be drawn into the bag as the temperature drops and the air contracts. The result may be moisture condensation within the bag. Extended exposure to these conditions may result in “caking” of the 3M™ glass bubbles to various degrees. To minimize the potential for caking and prolong the storage life, the following suggestions are made

  • Carefully re-tie open bags after use.
  • If the polyethylene bag is punctured during shipping or handling, use this bag as soon as possible, patch the hole, or insert the contents into an undamaged bag.
  • During hot and humid months, store in the driest, coolest space available.
  • If controlled storage conditions are unavailable, carry a minimum inventory, and process on a first in/first out basis.
