Product Description

Low Thermal Conductivity Low Density Reduce Cost Solutions

Product Description:

Hollow Glass Bubbles (HGB) are cost-effective, non-flammable, polyurethane molding components that offer enhanced acoustic insulation and low thermal expansion, while having a low density. HGB helps maintain dimensional stability, which is particularly important in demanding applications such as aerospace and military. They are also excellent for speciality applications such as thermal insulation, buoyancy, vibration dampening and noise reduction. HGB are extremely lightweight and have excellent thermal properties, making them ideal for a variety of applications. They are also very resilient to temperature changes and are able to maintain dimensional stability.
