Less noise and vibration with foam
Innovative foams not only damp noise and vibration they also filter particles and act as heat shields, cushions, and seals. Foam is versatile. Through innovative manufacturing and fabrication techniques, foam can take on a variety of properties. Foam can be water resistant, absorbent, porous

Foam-friendly fridges
Ever more stringent standards for energy efficiency force designers to plan carefully for the foam-insulation process. When a cabinet is filling with polyurethane foam, many physical and chemical reactions happen at once. Polymer formation reactions take place. The reaction of diisocyanate

Where foam fits in medical design
patients' mouths and gums. Foam can be processed to change its structure and properties. Foam offers designers a full palette of potential materials. They can use it to absorb, seal, filter, wick, cushion, insulate, or support loads. And to solve even more application problems, you can heat

Where Reticulated Polyurethane Foam's a Fit
Reticulated polyurethane foam is more than just a synthetic sponge. It can stop explosions, carry catalysts, and keep static from killing circuits. Edited by Jean M. Hoffman Reticulated polyurethane foam may appear to the uninitiated as nothing more than a synthetic sponge. But this lightweight

Foam Control
Foam is typically considered to be an undesirable property in a metalworking fluid. Since most metalworking fluids have good cleaning properties to help keep machines clean, they also foam when agitated. The quantity of foam that occurs, then, depends upon the chemical composition of a metalworking
