Open and Closed Cell Foam for Gaskets and Seals

Foam materials are lightweight, versatile, and durable, which makes them an ideal option for gaskets and seals across many of the industries that we serve.

CGR Products can fabricate and die cut a variety of foam and sponge rubber materials. Foam is incredibly efficient to work with as CGR can hold tolerances as low as .015” on materials with a firmer durometer.

closed cell sponge, die cut, kiss cutWe offer both open and closed cell foam materials, and our customers have used foam rubber gaskets and sealants across a number of industries including appliances, automotive, electronics, Open/Closed-Cell FoamHVAC, lighting, marine, power equipment, and many more.

The range of foam rubber materials we offer includes:

Foam rubber can fill large voids and gaps, and also has cushioning properties to help lessen impact between two substrates. Closed cell foam is perfect for sealing and helps reduce liquid and gas flow whereas open cell foam offers more flexibility and can be manufactured in either high or low density.

Foam can also be treated to have resistance properties depending on the intended application. It can be laminated and applied with adhesives that withstand intense pressure situations. Foams are naturally resistant to fire and burning and can be sealed to withstand many chemicals and acids. Additionally, foam is ideal for outdoor applications because it resists weathering, UV rays, and fungi.
