"Syntactic foam is a lightweight engineered foam consisting of manufactured glass hollow spheres embedded in a resin matrix. These hollow spheres typically range from 10 to 200 microns in diameter and are available in several materials, including glass, ceramic and polymers. This type of system has a very high compressive strength-to-weight ratio."
