Know before you buy
The 2.5mm option is ideal for keyboards with tighter internal clearances, while the 3.5mm option provides more substantial dampening for cases with extra room. Check the space between your PCB and the bottom of your keyboard case to ensure the foam won't cause interference with your components.
Yes, because the sheet is 43cm x 12cm and designed to be trimmed, it is compatible with most standard layouts, including full-size, TKL, and 60% keyboards. Simply measure your case's internal dimensions and use scissors to cut the foam to your specific shape.
While the primary goal is acoustic improvement, the PORON foam provides a slight amount of structural support. Most users find that it creates a more consistent, solid typing feel by eliminating the hollow, pingy resonance often found in stock keyboard cases.
No adhesive is required. The foam is designed to be cut to the exact dimensions of your case floor, allowing it to stay in place through a friction fit once the keyboard is reassembled.
PORON is a high-performance, open-cell polyurethane foam specifically engineered for superior compression set resistance and acoustic dampening. Unlike cheap craft foams, it maintains its shape over time and effectively absorbs high-frequency vibrations that cause keyboard ping.
