How Foam is Made

Our foam inserts are designed to keep the contents of our cases secure and safe. Whether the contents be military, medical, or electronic in nature, foam will keep them in place while the outside of the case takes a beating. So how is foam made? And what makes it so strong?

Foam’s strength comes from its chemical composition. To manufacture foam, two chemicals are used: polyol, a complex alcohol, and diisocyanate, a petroleum byproduct which reacts with alcohol. When these two ingredients are mixed and heated they form a liquid polymer called urethane, or polyurethane.

This hot liquid polyurethane is sprayed through a nozzle head onto wax paper that moves on conveyor belt. Carbon dioxide is also sprayed from another nozzle, which causes the liquid to expand and form a foam strip as it moves down the belt, which is trimmed and compressed into a viable shape. There are many gas bubbles in the polyurethane, which have to be released, otherwise the foam will become rock hard. The foam passes over heat lamps that dry the foam and cause the bubbles to expand and pop, which leaves behind spongy porous foam that can be molded into foam inserts.
