3M™ Glass Bubbles iM30K are engineered hollow microspheres made of soda-lime borosilicate glass with a true density of 0.60 g/cm³ and an excellent isostatic crush strength of 27,000 psi / 1860 bar.

Don't Wait, Reduce Part Weight
From start to finish, 3M™ Glass Bubbles iM30K are about helping the production process and the quality of finished parts. Toward that end, weight reduction of 15% or more can be achieved in injection molded parts. These substantial weight reductions don't come at the expense of quality. In fact, parts maintain strength, surface aesthetics and mechanical integrity with the use of 3M glass bubbles iM30K.

Improving Throughput
Reduce cycle time by 15-25% or more without compromising critical mechanical properties of finished parts. The secret? Faster cooling. Typically, cooling takes up most of a mold cycle. By using glass bubbles to reduce thermal mass, parts cool faster from the melt and cycle times can be considerably shortened. Fillers like talc and calcium carbonate may cost less but can actually increase part weight. Glass bubbles allow customers to make more parts per minute, per hour, per day and per year.

Do More for Sustainability
Importantly, our 3M glass bubbles iM30K contribute to environmental sustainability. With a high strength-to-weight ratio, glass bubbles are ideal for lightweighting materials like plastics and composites. According to a single-site carbon footprint study conducted by 3M on one class of glass bubble popular for use in plastic manufacturing, the addition of 3M™ Glass Bubbles to injection molded parts had a neutral impact on the carbon footprint of the finished part. Additionally, lightweighting has known advantages such as improved fuel economy, easier handling of hand-held plastic parts and reduced shipping costs.

Automotive Injection Molded Plastics
3M glass bubbles iM30K (PDF, 95 Kb) can be used for many automotive injection molded parts. A typical automobile has 300 kg of plastic parts that contribute to vehicle weight. Using our glass bubbles can reduce the weight of these parts by up to 15%, which can help improve fuel economy.

The 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
Filler loading
What are 3M™ Glass Bubbles?
Our 3M glass bubbles are engineered hollow glass microspheres that are alternatives to conventional fillers and additives such as silica, calcium carbonate, talc and clay. These low-density particles are used in a wide range of industries for many demanding applications to reduce part weight, lower costs and enhance product properties.

The chemically stable soda-lime-borosilicate glass composition of 3M glass bubbles provides excellent water resistance
Lower Viscosity
The 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. Additionally, the spherical shape helps the glass bubbles readily blend into compounds, making them adaptable to a variety of production processes, including spraying, casting and molding. They also offer greater survivability under demanding processing conditions, such as extrusion, injection molding and other high shear mixing processes.

The chemically stable soda-lime-borosilicate glass composition of 3M glass bubbles provides excellent water resistance. These bubbles are 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.
