3M™ GLASS BUBBLES  K20 have a density of 0.20 g/cc and an isostatic crush strength of 500 psi. These general purpose spheres have a good strength-to-density ratio and are designed for use in a variety of shallow water (e.g. up to 2,000 feet of sea water) buoyancy applications, as well as emulsion explosives.

Glass Bubbles S28HS are hollow glass spheres with a typical density of 0.28 g/cc and an isostatic crush strength of 3,000 psi. These glass bubbles are designed for numerous applications such as deep water syntactic foams and airless spray coatings. The bubbles produce strong, stable voids with low thermal conductivity, helping the coating achieve the necessary compressive strength. The S28HS Glass Bubbles offer a very good strength-to-density ratio and small particle size, making them suitable for a variety of applications such as buoyancy in oil and gas, airless sprayable paints and coatings, adhesives, mastics, sealants, SMC and other thermoset resin systems.

Glass Bubbles S38HS are hollow glass spheres with a typical density of 0.38 g/cc and an isostatic crush strength of 5,500 psi. These glass bubbles are designed for buoyancy and insulation in ultra-deep water applications in oil and gas drilling. The bubbles produce strong, stable voids and low thermal conductivity, helping coatings achieve the necessary compressive strength. These Glass Bubbles are designed for pipeline insulation in ultra-deep water applications and low density sheet moulding compounds (SMC).Applicaiton: Compounding, Insulation and Buoyancy, Paints and Coatings, Rubber and Plastic, Transportation.

3M™ W-210  CERAMIC MICROSPHERES are made of alkali alumino silicate ceramic and is one of our smallest high-strength ceramic particles with a typical d90 of 12 microns; it has a controlled particle size distribution. Formulating with these ceramic microspheres allows higher filler loadings while maintaining desired properties such as viscosity control. In addition, these engineered particles are added to many paints and industrial coatings to provide scrub and burnish resistance. Due to their smaller particle size, ceramic microspheres white grade W-210 are typically chosen over other ceramic microspheres for higher gloss formulations. Formulators may be able to extend resin in their formulation by adding 3M ceramic microspheres and potentially reduce cost
