Product Description
Inorganic Thermal Insulation Materials, Hollow Glass Bubble, HN20, Polyurethane Materials
Hollow Glass Bubble Description
Hollow glass bubble polyurethane materials (HGBPUs) are composite materials combining hollow glass bubbles with polyurethane resin. These small, lightweight hollow glass spheres serve as filler materials in coatings, adhesives, and composites.
When combined with polyurethane resin, they create lightweight materials with excellent insulation properties, ideal for building and construction applications including insulation panels, roofing, and wall systems.
Key Features
- High strength-to-weight ratio: Lightweight hollow glass bubbles provide exceptional strength relative to weight
- Excellent insulation properties: Ideal for energy-efficient building applications
- Moisture and chemical resistance: Suitable for outdoor applications with exposure to elements
