Our take on the Open Cell Polyurethane Foam: 4″ Thick, 13″ Wide, 13″ Long, Black Acrylic Adhesive Backing

This is a 4-inch-thick, 13-by-13-inch square of open-cell polyurethane foam with an acrylic adhesive backing, made by USA Sealing. The open-cell structure lets air and moisture pass through, so it breathes and compresses more readily than closed-cell foam. At medium hardness with a 20-40 Shore OO durometer and a 2 lb/cu ft minimum density, it sits in the middle of the foam range: softer than firm seating foam, denser than cheap packing foam. It suits cushioning, gasketing and padding jobs where a peel-and-stick layer of moderate support is wanted, though the small square and single thickness limit it to small projects.

Pros
  • Open-cell foam breathes and passes air and moisture
  • Acrylic adhesive backing bonds without separate glue
  • Medium hardness with 20-40 Shore OO durometer
  • 2 lb/cu ft minimum density holds up better than light packing foam
  • Cut square, ready to trim to size
Cons
  • Only 13 by 13 inches, so coverage is limited
  • Single 4-inch thickness with no other options
  • Open cells absorb water and are harder to clean than closed-cell foam
  • Medium grade is not a firm support foam

Questions and answers

What is open-cell foam good for?
Open-cell foam lets air and moisture through, so it is used for cushioning, padding, acoustic damping and breathable gaskets. It is not the right choice where water or vapor must be blocked.
How firm is this foam?
It is rated medium hardness with a 20-40 Shore OO durometer, which is soft enough to compress by hand but holds shape better than light packing foam. It is not a firm seating or structural foam.
Will the adhesive stick to wood and metal?
The acrylic adhesive backing is designed to bond to clean, dry, smooth surfaces such as wood, metal and plastic. Dusty or oily surfaces should be wiped first for a lasting hold.
Can I cut it to a smaller size?
Yes. Polyurethane foam trims easily with a sharp blade or serrated knife, and the square can be cut down to fit smaller areas. Cut before peeling the backing for cleaner edges.
Does it absorb water?
Yes. Open-cell foam soaks up water and takes time to dry, so it is a poor fit for outdoor or wet areas. Closed-cell foam is the better choice there.
