3Mâ„¢ Glass Bubbles iM16K are high-strength polymer additives made from a water-resistant and chemically-stable soda-lime borosilicate glass. These hollow glass microspheres can be used as a low density filler material ideal for plastic and rubber parts created from injection molding, extrusion processes, and/or other vigorous processing equipment (e.g., Banbury mixers, etc.), offering improved processing over many conventional fillers. They can reduce final part weight by 15% or more without compromising the mechanical integrity. 3Mâ„¢ Glass Bubbles iM16K help to reduce weight, improve dimensional stability, reduce shrinkage and sink marks, and contribute to material and process cost savings. They may be ideal additive materials for applications in the automotive, heavy truck, aerospace, electrical, sports and leisure, electronics, appliance and durable goods industries. 3M glass bubbles are also valuable in construction products such as polymer/wood composites and siding helping not only to reduce part weight, but also to improve dimensional stability and nail-ability.
