Introduction
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.
The chemically stable soda-lime-borosilicate glass composition
of 3M glass bubbles 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 K Series, S Series and iM Series are specially
formulated for a high strength-to-weight ratio. This allows greater
survivability under many demanding processing conditions, such
as injection molding. They also produce stable voids, which results
in low thermal conductivity and a low dielectric constant. 3M glass
bubbles are available in a variety of sizes and grades to help you
meet your product and processing requirements.

thermal conductivity of a composite will depend on the matrix
material and volume loading of 3M glass bubbles.
Thermal Stability
Appreciable changes in bubble properties may occur above 1112 F
(600 C) depending on temperature and duration of exposure.

Glass Bubbles K, S and iM Series

Minimum storage conditions should be unopened cartons in an
unheated warehouse.
Under high humidity conditions with an 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:
1. Carefully re-tie open bags after use.
2. 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.
3. During humid summer months, store in the driest, coolest
space available.
4. If good storage conditions are unavailable, carry a
minimum inventory, and process on a first in/first

out basis.
Dusting problems that may occur while handling and processing
can be minimized by the following procedures:
1. For eye protection wear chemical safety goggles. For
respiratory system protection wear an appropriate NIOSH/
MSHA approved respirator. (For additional information
about personal protective equipment, refer to Material
Safety Data Sheet.)
2. Use appropriate ventilation in the work area.
3. Pneumatic conveyor systems have been used successfully
to transport 3M glass bubbles without dusting from
shipping containers to batch mixing equipment. Static
eliminators should be used to help prevent static charges.
Diaphragm pumps have been used to successfully convey
3M glass bubbles. Vendors should be consulted for
specific recommendations.
3M glass bubble breakage may occur if the product is improperly
processed. To minimize breakage, avoid high shear processes such
as high speed Cowles Dissolvers, point contact shear such as gear
pumps or 3-roll mills, and processing pressures above the strength
test pressure for each product.
Health and Safety Information
For product Health and Safety Information, refer to product label
and Material Safety Data Sheet (MSDS) before using product.
