Hollow Glass Microspheres for Low-Density Filler are premium hollow glass microbubbles. Each microsphere features a thin glass shell with air-filled hollow cavity, delivering ultra-low bulk density. When incorporated into SMC sheet molding compound and other plastic composite systems, these microscopic hollow beads reduce overall component weight significantly without severe sacrifice of mechanical performance. The spherical shape improves resin flow during molding, lowers compound viscosity and
Chemical Identity / TDSProduct Name: Hollow Glass Microspheres Chemical Type: Hollow Soda-Lime Glass Microbubbles Physical Form: Free-flowing ultra-fine hollow microbead powder Core Benefit: Ultra-light hollow glass bubbles as lightweight filler for SMC composite weight reduction
Key PerformanceThe hollow core structure brings outstanding weight reduction effect. Spherical morphology ensures good flowability in thermoset resin systems. It helps reduce part density and improves dimensional stability. Particle density and crush strength grades can be customized to match SMC molding pressure. Loading dosage and mixing process parameters refer to manufacturer TDS.
Applications
ComplianceInorganic lightweight hollow glass filler. TDS, MSDS and relevant compliance certificates can be provided for export audit upon request.
