Ultra-fine high-strength low-density grade This grade belongs to the Hainuo Low-Density series (true density 0.30–0.50 g/cm³). Produced from soda-lime borosilicate glass, it consists of micron-scale hollow spheres offering light weight with high strength, thermal insulation, chemical resistance and a low dielectric constant — a key functional filler in the advanced composites value chain. 0.30–0.34 Density g/cm³ 28 Strength MPa 4,000 Strength psi ≤20 D50 µm NO1 Highlights
