Product Description
Polyurethane Molding, Hollow Glass Bubble, HN25HS, Injection Molding, Synthetic Foam.
Hollow Glass Bubble Description
The theory behind using hollow glass bubbles in polyurethane molding involves reducing the weight of the final product while maintaining structural integrity. Hollow glass bubbles, also known as glass microspheres or microballoons, are tiny spheres made of glass with a hollow center. Their lightweight and low-density properties make them ideal for reducing polyurethane product weight.
Hollow Glass Bubbles Applications
- Building and construction: Polyurethane products with hollow glass bubbles are applied in roofing and flooring. Their lightweight nature enables easy installation and transportation, while maintaining strength and durability.
- Marine and boating: The polyurethane foam with hollow glass bubbles is commonly used in maritime scenarios including boat building and repair applications. Its lightweight and durable features ensure structural integrity for hulls, decks, and other components.
