Hollow Glass Microspheres K15 Equivalent is high-performance hollow glass microbubble powder, equivalent to K15 grade hollow glass bubbles. With thin glass shell and air-filled hollow interior, these microspheres feature ultra-low bulk density. When added into plastic composite or coating resin systems, they reduce the finished product density effectively and achieve weight-saving effect. The spherical structure provides good flow property, lowers viscosity increase during mixing, and improves d
Chemical Identity / TDSProduct Name: Hollow Glass Microspheres K15 Equivalent Chemical Type: Hollow Soda-Lime Glass Microbubbles Physical Form: Free-flowing ultra-fine hollow microbead powder Core Benefit: K15 equivalent low-density glass bubbles for weight reduction in plastic composite and coating
Key PerformanceThis K15 equivalent glass bubble delivers ultra-low density and good dispersion in resin systems. It brings lightweight effect without sharp rise of system viscosity. It can be customized for different processing pressure requirements. Recommended loading ratio and mixing speed refer to manufacturer TDS.
Applications
ComplianceInorganic lightweight hollow glass filler. TDS, MSDS and relevant compliance certificates can be provided for export audit upon request.
