Details
Highlights
- Floated series has 99% floaters by volume to help you achieve lighter composites
- Decreases weight, increases buoyancy and may lower material costs
- Provides excellent water and oil resistance for use in underwater applications
- Surface treated to improve mechanical properties of the composite
- Improves dimensional stability
- Versatile use – adaptable to a variety of production processes
3M™ Glass Bubbles A20/1000 have a density of 0.20 g/cc and an isostatic crush strength of 1,000 psi. They have less than 1% sinkers by volume and are surface treated to be compatible with buoyancy module manufacturing. Like other 3M™ Glass Bubbles in our floated product series, this product is ideal for use in a number of aerospace and oil and gas applications.
A Great Product Rises to the Top
3M™ Glass Bubbles A20/1000 is part of the floated product series and has less than 1% sinkers by volume. This means that we get 99% floaters by volume using a universally held process to assure that you get perfectly formed 3M™ Glass Bubbles, not sinkers. Here’s how it works: we put a population of bubbles of a given specification into water and take only the ones that float to the top. This is the oldest, simplest and perhaps most reliable method to ensure bubbles are whole and intact, while improving the strength-to-density ratio. In short – we take only the cream of the crop and give you bubbles that are less dense at the same nominal strength.
3M™ Glass Bubbles Floated Series
3M glass bubbles in our floated series offer the same combination of strength and light weight as standard 3M glass bubbles, with an added surface treatment. A20/1000 glass bubbles have methacrylato chromic chloride surface treatment. This special coupling agent expands this product’s uses. It can be used in high-tech applications such as aerospace and hydrospace syntactic foam and radomes. Glass bubbles in the floated series are available in a variety of sizes and grades for various product and processing requirements.
Strength-to-Weight Ratio
The benefits don’t end there; although 3M glass bubbles A20/1000 have thin walls, they have good isostatic crush strength of 1,000 psi, meaning they can survive both the rigorous demands of processing and water pressure at depth. A20/1000 bubbles have a fractional survival rate of 88% or more, at 1,000 psi for consistent performance and greater survivability. The unique spherical shape of these bubbles offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow a
