Our take on the Foam Sheet, Water-Resistant Closed Cell, 12 in W, 24 in L, 1/2 in Thick, Black

This is a 12 in by 24 in sheet of black EPDM closed cell foam, 1/2 in thick, with acrylic adhesive on both sides. EPDM handles weather, ozone and water well and stays flexible from -90 F to 275 F, so it suits sealing, gasketing and cushioning where rubber would crack or absorb water. Density is 18 lb/cu ft and tensile strength 70 psi, which is firm but not rigid; the smooth skin-free surface bonds cleanly. Against open cell sponge or plain neoprene, it resists water and aging better, but it is less oil resistant and the double-sided adhesive limits it to bonding two surfaces rather than wrapping.

Pros
  • Closed cell EPDM resists water, ozone and UV
  • Wide temperature range from -90 F to 275 F
  • Adhesive on both sides speeds assembly
  • Smooth, skin-free surface for clean bonds
  • Firm 11 psi at 25 percent deflection holds shape
Cons
  • EPDM swells in oils and fuels
  • Double-sided adhesive is awkward for wrapping or shimming
  • 1/2 in thickness is bulky for tight gaps
  • 70 psi tensile strength tears under heavy shear

Questions and answers

What is EPDM foam good for?
Sealing, gasketing and cushioning outdoors or in wet areas. It resists water, ozone and UV and stays flexible across a very wide temperature range.
Will the adhesive hold outdoors?
The acrylic adhesive is rated from -30 F to 230 F, so it handles normal outdoor temperatures. Clean and dry both surfaces and press firmly for a full bond.
How does it compare with neoprene?
EPDM beats neoprene on weather and water resistance and costs less. Neoprene is the better pick where oil or fuel contact is likely.
Can I use it as a vibration isolator?
Yes. At 18 lb/cu ft and 11 psi at 25 percent deflection it is firm enough to damp vibration under light loads. Heavier loads need a denser or thicker pad.
Is it safe for outdoor use?
Yes. EPDM is one of the most weather-stable rubbers and does not absorb water like open cell foam.
What is in the box?
One 12 in by 24 in black EPDM sheet, 1/2 in thick, with acrylic adhesive on both sides.
