3M™ Glass Bubbles VS5500 glass bubbles have a true density of 0.38 g/cm3 and an isostatic crush strength of 5500 psi / 379 bar.
Reducing Weight – Improving Performance
3M™ Glass Bubbles VS5500 are designed specifically for use as lightweight polymer additives. Their smaller particle size increases wettability, allowing higher volume loading with less increase in viscosity. . Most important, our glass bubbles can help reduce plastisol weight up to 50 percent to help your customers achieve their vehicle weight reduction targets.
An Innovative Alternative
3M™ Glass Bubbles VS5500 are a versatile alternative to traditional polymer fillers, offering a number of competitive advantages for automotive seam sealing and underbody coatings. For starters, these hollow microspheres are significantly lighter than most other fillers – including previous generations of 3M glass bubbles used in this application. This helps reduce vehicle weight and simplifies processing. Engineered from chemically-stable, soda-lime borosilicate glass, this filler is water and oil resistant, which helps prevent damage from rust or other common automotive liquids. The intrinsic hardness of 3M glass bubbles also contributes to the strength and durability of the sealant or coating, which helps protect against scratching and chipping.
Reducing the Cost of Compliance
By contributing to lower vehicle weights, 3M™ Glass Bubbles VS5500 can help automotive manufacturers meet emission reduction targets. And by switching to 3M glass bubbles, producers can achieve mandated reductions in their use of PVC without relying on more expensive resins like acrylic.
