3M™ Glass Bubbles S32HS are hollow microspheres made of soda-lime borosilicate glass with a true density of 0.32 g/cm³ and an isostatic crush strength of 6000 psi / 420 bar.

S32HS Glass Bubbles have an excellent strength-to density ratio and can offer greater survival rates than other lightweight additives under demanding processing conditions. These Glass Bubbles can help reduce weight and thermal expansion and can be used in a variety of applications such as automotive, construction, marine, and paints and coatings. The S series Glass Bubbles generally offer smaller particle sizes than the K series. Particularly in automotive applications they can help with attainment of class A surface properties in SMC composites.
