Epoxy spheres are lightweight, pressure-resistant functional fillers with high-performance composite material walls, ranging in size from millimeters to centimeters, with typical diameters ranging from 2 to 50 mm. Epoxy spheres are characterized by low density, high strength, good sphericity, corrosion resistance and anti-aging. Depending on the strength grade, the true density generally ranges from 100 to 600 kg/m³.

Three-phase composite SBM
Three-phase composite SBM is based on two-phase composite SBM by adding a component, namely hollow epoxy spheres. Although the addition of large-sized hollow epoxy spheres reduces the material strength, its performance is still superior to chemically foamed materials, and it has good safety and stability. Therefore, compared with the other two types of buoyancy materials, three-phase composite SBM is very suitable for use in medium and deep sea environments.
Application of epoxy sphere
Epoxy spheres, as functional lightweight filler materials, can be used in high-performance lightweight composite materials, and have properties such as weight reduction, reinforcement, sound insulation, heat insulation and vibration reduction, making them suitable for marine engineering, aerospace, automotive and construction fields.
