Comparative Analysis: Melamine Eraser Sponges vs High-Density PU Sponges
An in-depth material comparison between open-cell melamine foam and high-density polyurethane sponges for industrial surface cleaning, stain removal, and ceramic finishing.

Industrial surface cleaning requires specialized sponge polymers depending on whether micro-abrasion or liquid absorption is required. Two dominant materials lead global industrial supply chains: Open-Cell Melamine Foam and High-Density Polyurethane (PU) Foam.
| Property | Melamine Eraser Sponge | High-Density PU Sponge |
|---|---|---|
| Polymer Base | Formaldehyde-Melamine-Sodium Bisulfite Resin | Polyurethane Polyol Compound |
| Cell Structure | Open-cell 3D Network Filaments | Controlled Cellular Foam Grid |
| Primary Application | Water-only stain scrubbing & glaze scuff removal | Heavy liquid pickup, wiping & chemical application |
Melamine foam acts as ultra-fine sandpaper at the microscopic level. The hard resin filaments break down stubborn scuffs on ceramic sanitaryware, mold surfaces, and glass without chemical solvents, preserving surface gloss while achieving zero residue cleanups.
