Product Description
Polyurethane Molding, Hollow Glass Bubble, HN32HS, Synthetic Material, Thermoplastic.
Hollow Glass Bubble Description
Polyurethane is a relatively expensive material, and cost is a major consideration in many applications. The effectiveness of polyurethane is measured by its mechanical properties, thermal insulation, and weight.
Hollow glass bubbles can play significant role in reducing its cost while maintaining its properties. The low density bubbles allows them to occupy a larger volume within the polyurethane, reducing the amount of solid polyurethane needed to achieve the required properties. This will lead to significant cost savings as less material is required to get same performance.
Hollow Glass Bubbles Applications
- Spray foam insulation: Used in buildings and homes to provide thermal insulation. The low thermal conductivity improves insulation properties while reducing weight and cost.
- Automotive components: Used in seat cushions, door panels, and instrument panels. The low weight and high strength properties improve fuel efficiency and reduce vehicle weight.
