D32/4500 glass bubbles have a density of 0.32 g/cc and an isostatic crush strength of 4500 psi. They have less than 1% sinkers by volume and are surface treated with methacrylato chromic chloride.
Application Guide
Listed below are key applications for D32/4500 glass bubbles. Documents specific to the application are listed to the right.
Density Reducing Agents for Buoyancy
With a crush strength of 4500 psi and a density of just 0.32 g/cc, 3M Glass Bubbles D32/4500 are ideal for deep water buoyancy applications, especially in underwater vehicles. In these applications, the high strength-to-weight ratio of D32/4500 glass bubbles helps to increase bouyancy while withstanding the pressure of deep water.
Paints and Coatings
3M glass bubbles offer a variety of benefits to light weight, high-build elastomeric roof coatings, anti-condensation coatings, etc. Here are some of the benefits:
