Neoprene Foam Open-cell and Closed-cell


While the difference between neoprene open-cell foam and closed-cell foam is not that difficult to understand, it is important to understand that both types of cell matrix structures are used in expanded cellular rubber materials, but they serve different purposes.

These are some of neoprene closed-cell foam (often called CCNS) typical uses:

  • Very good for weather stripping and box sealing
  • Closed-cell construction is waterproof with good ozone and intermittent oil resistance
  • General sealing and cushioning applications where low compression force is desirable
  • Good for some refrigerants

If you have an application requiring high temperature capabilities and excellent ultraviolet and weathering resistance, or FDA grade for use in contact with food, we recommend our silicone foam.

Please call Gardico, Inc. if you need technical assistance in selecting among our neoprene synthetic rubber, custom polyurethane foam and our silicone foam for your application.

Polyurethane Foam


We provide foam and sponge materials for a broad range of applications including our neoprene foam open-cell and closed-cell foam, Poron® polyurethane, and silicone foam.

We also offer microcellular polyurethane foam that is finding greater usage applications in door seals for equipment boxes because of its excellent resistance to compression set and impact absorption. Although open-cell, it seals liquids when compressed 25% or more. We supply microcellular polyurethane foam known as Poron® as one of our design solutions for:

  • Gasketing
  • Sealing – especially door seals for equipment boxes
  • Energy absorption

Some of its outstanding properties and characteristics for industrial applications include:

  • Excellent compression set resistance
  • High resiliency
  • Low out-gassing and non-corrosive to metals
  • Good chemical resistance
  • Easy to fabricate
  • Clean die-cutting properties
  • Performs over temperature range of -40-deg to 198-deg F

We have technical staff available to discuss your application and the best recommendation to meet its requirements with neoprene foam, silicone foam, or Poron® polyurethane. Call us today!

Silicone and Other Foams

We supply solid silicone and silicone foam rubber in both closed-cell and micro-cellular open-cell available in sheets, strips or cut parts, with or without pressure-sensitive adhesive, as we also supply our neoprene foam open-cell and closed-cell foam and sponge rubber, and our polyurethane foam.

As a supplier of both solid and silicone foam rubber we see great acceptance and wide use because of its:

  • Superior tolerance to heat and fire
  • Resistance to weathering
  • Wide range of chemical resistance
  • Water sealing capabilities of closed-cell foam
  • Dust sealing benefits of open-cell and closed-cell foam
  • Long term performance relative to UV and ozone resistance

Silicone sponge and silicone rubber sheets can be readily fabricated into gaskets and cushioning pads, and also for FDA grade products used in contact with food.
