Product Description
Synthetic Foam, Hollow Glass Bubble, HN38, Polyurethane Molding, Buoyancy Material.
Hollow Glass Bubble Description
The properties of synthetic foam can be largely determined by changing production parameters such as the matrix material, filler composition, microsphere size, wall thickness, and volume ratio. These foams offer significant advantages including ease of production, reduced weight, increased rigidity, buoyancy, and cost efficiency.
Their exceptional performance characteristics include resistance to compression and hydrostatic loads, good impact and fatigue response, and excellent abrasion and chemical resistance, making them ideal for diverse construction applications.
Applications
- Marine components: Used in boat hulls, decks, and superstructures for lightweight durability
- Sports equipment: Ideal for surfboards, kayaks, and paddles requiring strength with minimal weight
- Packaging: Creates protective, lightweight materials that reduce shipping costs while safeguarding products
Product Advantages
Reduces shrinkage and enhances frame stability in composite materials
