Product Description
Synthetic Foam, Hollow Glass Bubble, HN25HS, Injection Molding, Polyurethane Molding
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. These glass microspheres are tiny spheres with a hollow center, offering lightweight properties and low density - ideal for reducing polyurethane product weight.
The purpose of using hollow glass bubbles in synthetic foam is to reduce foam density while strengthening mechanical properties. The glass bubbles create a composite material with lower density while maintaining original strength and stiffness.
Hollow Glass Bubbles Applications
- Building and construction: Used in insulation, roofing, and flooring applications where lightweight properties combine with strength and durability.
- Sports equipment: Used in helmets, pads, and shoes for lightweight protection and shock absorption.
