Melamine foam

From Wikipedia, the free encyclopedia

The microfine structure of melamine foam, creating very hard, tiny fibres which scour some surfaces clean.

Melamine foam is a foam-like material consisting of a formaldehyde-melamine-sodium bisulfite copolymer. The foam, because of its microporous properties, may remove otherwise "uncleanable" external markings from relatively smooth surfaces. For example, it can remove crayon, magic marker, and grease from painted walls, wood finishings, and grime from hub caps.

The open cell foam is not only microporous, but its polymeric substance is also extremely hard, meaning that it works like sandpaper but on a smaller scale, getting into tiny grooves and pits in the subject being cleaned. On a larger scale, the material feels soft. Because the bubbles interconnect, its structure is more like a maze of fibreglass strands than like the array of separate bubbles in, for example, styrofoam.

The substance needs to be dampened to work properly. It does break down rather rapidly, so a given block of foam generally lasts only a single intensive scrubbing session, though it can be used repeatedly for much smaller marks.

While the name-brand "Magic Eraser" is made by Mr. Clean (Procter & Gamble), the foam itself is manufactured in Germany by BASF under the name "Basotect" and was already a common product before this new use was discovered. Other companies have also begun marketing it for its cleaning properties, either under other names, like Coralite Ultimate Sponge, or as a generic product.

Melamine foam has been used for over 20 years as insulation for both pipes and ductwork. It also has a long history as a soundproofing material for projects like studios, sounds stages and auditoriums. The low smoke and flame properties of melamine foam are very beneficial toward safety concerns^{[citation needed]}.

The Magic Eraser earned the Electrical Audio Intern's Corner "Key Buy" award in 2003.
