Glass Bubbles

Bisley Hollow Glass Microspheres (HGMs) are ultra-light, hollow spheres made from borosilicate glass. Their unique structure combines a thin, durable shell with an empty core, giving them a rare combination of strength, low density, and versatility. Whether used to reduce weight, improve insulation, or enhance performance, HGMs are trusted across industries from construction to aerospace.

Key Benefits

Lightweight Efficiency
HGMs significantly reduce density in composites, coatings, cements, and plastics — helping lower material usage and overall weight without compromising strength.
Thermal & Acoustic Insulation
The hollow core traps air, enhancing both thermal and sound insulation. This makes them ideal in construction materials, coatings, and specialty applications requiring heat or noise control.
Durability & Stability
Non-combustible and nonporous, HGMs resist water, chemicals, and high temperatures. Their strong yet lightweight shells withstand compression and maintain integrity in demanding environments.
Enhanced Performance
Their spherical shape improves flow, processing, and finish quality in coatings and polymers. They also contribute to abrasion resistance, reduced shrinkage, and better dimensional stability.
Cost-Effectiveness
By lowering resin demand and improving filler loading, HGMs deliver cost savings alongside performance advantages.
