Product Overview

Description


1. Description

Hollow glass microspheres ( also known as glass bubbles ) are hollow glass spheres made of chemically stable Soda-lime-borosilicate glass with thin walls(wall thickness 1~3.5μm). We have several grades available with true density ranging from 0.20g/cc~0.60g/cc, Sinosteel hollow glass microspheres can be used as lightweight functional additives for Composites,Thermal insulation paints/coatings, Sealant/adhesives, Low density cementing slurries and many more applications with very competitive quality and price.
