The secret to cleaning up contaminated water may lie in the cheap, common polyurethane foam used in mattresses. In a study published in the journal Nature Sustainability this week, scientists tested ...

Scientists from Tomsk Polytechnic University jointly with the University of Lille (France) have developed a new material capable of purifying water effectively from oil products. It is based on an ...

Reticulated polyurethane foam may appear to the uninitiated as nothing more than a synthetic sponge. But this lightweight material is strong enough to handle industrial applications ranging from sound ...

Scientists say that they have invented a sponge made of common polyurethane foam treated to absorb up to 90 times its weight in oil. Photo: Argonne National Laboratory Oil and water don’t mix, the ...

Researchers at the University of Twente have developed a method to recycle polyurethane foam from mattresses and furniture and also household sponges. They did this safely, without using toxic ...

Polyurethane foam can be divided into two categories, such as open-cell and closed-cell foam. The former is a plastic with incomplete cell walls and include holes through which air and liquid can ...
