\n

Quick answer:<\/strong> Melamine foam and polyurethane foam do different jobs, so they rarely compete for the same position on a product line. Melamine is a rigid, open-cell resin foam that behaves like a very fine abrasive: it erases marks instead of soaking up liquid. Polyurethane (PU) is a soft, elastic foam that holds water, releases it when squeezed and survives thousands of compression cycles. Most successful OEM programs we run use both – PU for the soft body and the absorption, melamine for the erasing face.<\/p>\n<\/div>\n

How the Two Foams Are Made<\/h2>\n

Melamine foam begins as a melamine-formaldehyde resin that is foamed and cured into a block. The result is rigid and open-celled, and the cell walls are thin and slightly brittle – press a fingernail in and they shear off. That brittleness is the product, not a defect. The foam is a consumable abrasive, which is exactly why it crumbles as it lifts marks off a wall.<\/p>\n

Polyurethane foam runs on different chemistry. Polyols react with isocyanates into an elastic skeleton, so the cell walls stretch and recover instead of shearing. The foam carries water and detergent to the surface, then lets go of it when you squeeze. It does not erase anything on its own.<\/p>\n
