Product Introduction

Cellular Glass, made from glass powder and additives baked at high temperatures, is a premium thermal insulation material. It features light density, low thermal conductivity, moisture resistance, non-combustibility, high strength, chemical corrosion resistance (except to hydrofluoric acid), and stability across extreme temperatures. Durable and fire-resistant, it excels in harsh environments like deep cold, underground, and chemical exposure, making it ideal for petroleum, chemical, shipbuilding, and military industries. Known as a “permanent insulation material,” it requires no replacement over time.

Feature:

  • Lightweight: Ideal for construction due to low density.
  • Thermal insulation: Excellent heat retention for energy efficiency.
  • Corrosion resistance: Endures water, chemicals, and solvents.
  • Sound absorption: Reduces noise transmission for comfort.
  • Compression resistance: Maintains shape under weight and pressure.
  • Fire resistance: High resistance to fire for safety.
  • Plasticity: Easily shaped and installed.
  • Eco-friendly: Made from recyclable materials.

Application:

  • Building insulation: Enhances energy efficiency in structures.
  • Industrial insulation: Reduces energy loss in equipment.
  • Chemical materials: Corrosion-resistant fill for tanks.
  • Sound insulation: Minimizes sound transmission.
  • Transportation: Provides thermal and sound insulation.
  • Furniture decor: Improves home comfort with filling and panels.
  • Healthcare: Enhances comfort in medical settings.
  • Garden agriculture: Optimizes plant growth conditions.
