Application of hollow glass microspheres in the synthetic foam board
The composite material with hollow glass microspheres and resin is commonly referred as synthetic foam board, its main characteristics is 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 etc. 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 its closed cell structure.

Hollow glass microspheres occupy less surface area, low oil—absorption rate, and evenly disperse in mixture. Its easy compression and integration permit high filler loadings. It significantly reduces the consumption of resins, increases the amount of filler, and effectively reduces VOC indicators,...
