Product Details

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.
