It depends on whether it is 'open-cell' (absorbent, like a bath sponge) or 'closed-cell' (water-resistant). Most sponge rubber used for seals and gaskets is closed-cell to prevent water ingress.
Common uses include weather stripping, padding for furniture and sports equipment, gaskets and seals in machinery, anti-vibration mounts, and protective packaging.
Use a sharp utility knife, scalpel, or electric knife. For thick sheets, a bandsaw with a fine-tooth blade is often used in workshops. A straight edge as a guide is recommended for clean cuts.
