3M™ Glass Bubbles S60/18,000 S

3M™ Glass Bubbles S60/18,000 S 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 S60/18,000 S 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 S60/18,000 S is 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.

Storage & Handling

Storage Conditions
  • To help ensure ease of storage and handling while maintaining free-flowing properties, 3M™ Glass Bubbles have been made from a chemically stable glass and are packaged in a heavy-duty polyethylene bag within a corrugated container.
  • Minimum storage conditions should include 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 air contracts. This effect may lead to moisture condensation in the bags. 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 opened bags after use.
  2. If the polyethylene bag is punctured during shipping or handling, seal the hole as soon as possible 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 diskharge.
  4. Diaphragm pumps have been used to successfully convey 3M glass bubbles. Vendors should be consulted for specific recommendations.
