Hollow Glass Microspheres Overview
Hollow glass microspheres (HGMs), also known as glass microballoons or glass bubbles, are small, hollow spheres made of glass with diameters ranging from 1 to 100 microns. These microspheres are created through a specialized process where a blowing agent is added to a glass mixture and heated until expansion forms hollow spheres.
Primary Applications
- Fillers: Used in composites, plastics, and coatings to reduce weight while improving strength
- Insulation: Enhances thermal and acoustic properties in insulation boards, paints, and coatings
- Adhesives & Sealants: Improves mechanical properties and reduces shrinkage in bonding applications
