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.

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.

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.

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.

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.

3M
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.

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.

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.

SECTION 11 - Toxicological Information
Effects of Acute Exposure: Slightly hazardous in case of skin contact (irritant), of eye contact (irritant),
or in case of inhalation (initant).
Effects of Chronic Exposure:
Irritancy of Product: Potential irritant for Skin Sensitization,
Respiratory Sensitization: Upper Respiratory Irritant: May aggravate pre-existing respiratory conditions.
Levels of Respirable Crystalline Silica in Sil-Cell, if present at all, are undetectable. Because it
is known that long-term inhalation of respirable crystalline silica can cause disabling lung disease
(silicosis), OSHA has published revised exposure limits. The current Action Level (AL) and Permissible
Exposure Limit (PEL) as an average during 8 hours of continuous exposure are 25 pglm3 (Air) and
50 pglm3 (Air), respectively.
Carcinogenicity: These products contain less than 0.1Yo cryslalline silica, and low percentages of
particles of respirable size, hence present very low risk.
