As industries push for lighter materials, improved insulation, and enhanced performance, advanced fillers are becoming critical in modern material engineering. One of the most effective solutions is Hollow Glass Microspheres (HGM) — and the 32P4000 grade stands out for its balance of low density and high crush strength.

What Are Hollow Glass Microspheres?

Hollow Glass Microspheres are microscopic, thin-walled glass spheres filled with air or gas. These inorganic, non-metallic materials function as lightweight performance fillers used to improve:

  1. Weight reduction
  2. Thermal insulation
  3. Mechanical performance
  4. Dielectric properties
  5. Processability

They are widely used in oil & gas, aerospace, coatings, sealants, and buoyancy materials.

Introducing 32P4000 Hollow Glass Microspheres

The 32P4000 grade is engineered for applications requiring structural integrity while minimizing weight.

Core Performance Advantages

Significant Weight Reduction

With a density far lower than traditional mineral fillers, 32P4000 helps manufacturers reduce composite weight without sacrificing strength.

High Crush Strength

A 28 MPa crush strength ensures the microspheres maintain integrity during mixing and processing, protecting final product performance.

Thermal Insulation

The hollow structure traps air, reducing thermal conductivity — ideal for insulation coatings and energy-saving materials.

Low Dielectric Constant

Useful in applications where electrical insulation or signal transmission stability is important.

Excellent Flowability

Spherical geometry improves processing behavior in resins, coatings, and adhesives.
