Application of hollow glass microspheres in the synthetic foam

The composite material of hollow glass microspheres and resin is commonly referred as synthetic foam with its main characteristics of low density. With high mechanical properties, it is a wide set of multifunctional composite materials for vibration damping, insulation, fire prevention. Now it is mainly used in manufacturing of aircraft, spacecraft, and ship. The synthetic foam with addition of hollow glass microspheres has not only the porous structure, but also makes core materials own low moisture absorption and high compressive strength due to the closed cell structure.
