Closed Cell Foams

Closed Cell Foams are fabricated into seals, gaskets, anti-rattles, barriers, support blocks, seating inserts and packaging supports. The closed cell market offers Neoprene, EPDM, EVA, ECH, EPP, EPE, EFO, PVC, XLPE, Poron & Hyper-cel. There have been many different types of closed cell foams designed specifically around specification criteria. Closed cell foam is made of uniform cells that maintain their own shape. The individual cell structures are completely closed with their own walls. This compressed structure prevents air or moisture to enter inside the foam; which makes closed cell foam much more rigid and stable than open cell foams. All of these foams mentioned above have a wide range of thicknesses and come in standard colors. Typically, closed cell foams have excellent physical properties that block UV light and are chemical resistant. All closed cell foams can be supplied with and without pressure sensitive adhesive on one or both sides.

Closed Cell Foam vs. Open Cell Foam

Closed Cell Foams achieve an adequate seal upon 30% compression between the two surfaces. This type of foam permanently isolates the flow of outside elements so that the cold, warm or moist environments never infiltrate pass the sealed area. High and low densities are available and most closed cell foams have excellent resistance to heat. Closed Cell Foams are manufactured in buns, sheets, rolls, castings, and extruded. Black is the standard color… with many colors being an option depending on the industry and application.

Open Cell Foams must be compressed down to semi-solid pieces in order to seal out air and moisture. This type of foam allows air, water and other elements to pass through, reducing their ability to insulate once moisture is absorbed. This type of foam is more flexible and returns to its original state after compression is released. High and low densities are available and normally open cell foams have low heat resistance. Open Cell Foams are manufactured in buns, sheets, rolls, custom profiles and contoured shapes. The entire color wheel is becoming more prevalent in the polyurethane industry, due to the unique uses where appearance plays a major role.
