These are four 6 x 6 inch squares of closed-cell neoprene foam, each 3/4 inch thick, with a self-adhesive backing. The thickness is the standout: most adhesive foam sheets sold for padding and sealing are 1/8 to 1/4 inch, so these suit jobs that need real bulk, like lifting a washing machine off a floor or deadening sound under a speaker. The closed-cell structure means the foam does not soak up water, and the maker rates it for roughly -50°C to 150°C. It suits DIY sealing, vibration and noise damping, and craft padding; it is overkill for thin gap filling, where a thinner sheet cuts more cleanly.

These are self-adhesive foam padding sheets made of high-density closed-cell neoprene. The pack has 4 black sheets, each measuring 6 x 6 inches and 3/4 inch thick. The foam is flexible, scratch resistant, water resistant and wear resistant. It withstands temperatures from -50°C to 150°C, so it can be used indoors and outdoors.
Each sheet has a high-adhesion backing that sticks to wood, metal, tile, plastic and other smooth surfaces. It does not slide, and it leaves no sticky residue when removed. The non-slip foam can hold furniture and appliances in place on hardwood or ceramic tile. It also insulates sound and absorbs shock, which reduces noise transfer under speakers, washing machines or AC units.
The sheets cut easily with scissors to any shape. They can be used as door or window seals to block drafts, dust, wind and moisture, and as craft padding or appliance mats. Before use, make sure the surface is clean and dry, then press each pad firmly for 30 seconds.
