Product Description
Polyurethane Molding, Hollow Glass Bubble, HN42, Artificial Stone
Hollow Glass Bubble Description
The hollow glass bubbles used in this process are small, lightweight, and have a high compressive strength. They are used as a filler material in the polyurethane matrix to provide structural support and reduce the overall weight of the molded part.
This process produces lightweight, high-strength, and thermally insulating molded parts. Users simply add hollow glass bubbles into mixture of polyurethane resin then inject the composite material into a mold. After solidifying the shape, the finished product can be used for sanding, painting, and other applications.
Hollow Glass Bubbles Applications
- Design flexibility: Polyurethane molding with hollow glass bubbles can produce products in a wide range of shapes and sizes, making it versatile for manufacturing.
- Weight reduction: The hollow glass bubbles reduce the overall weight of molded products, ideal for applications where weight reduction is necessary.
