Durable enough to be used in seat cushions, this flexible polyurethane foam provides gentle cushioning support.

Flame-Retardant Super-Cushioning
Polyurethane Foam Sheets and Strips

When these sheets and strips are exposed to flames, the surface chars to create a protective barrier that prevents melting, dripping, and the possibility of spreading fire.

Resilient Polyurethane Foam Sheets and Strips

Even after extended compression, these high-performance polyurethane foam sheets and strips bounce back to shape faster than any other foam we offer. Also known as Poron urethane, they also stand up to wear caused by rubbing and scraping.

Ultra-Conformable Polyurethane
Foam Sheets and Strips

Commonly called memory foam and Confor, these sheets and strips have the best cushioning qualities of all the foam we offer.

Water-Resistant Resilient
Polyurethane Foam Sheets and Strips

Good for tough vacuum-sealing and low closure-force applications, these polyurethane foam sheets and strips have open/closed cells to keep water, air, and gases from being absorbed when they are compressed at least 25%. Even after extended compression, all bounce back to shape faster than other foams we offer.

Laminated Super-Cushioning
Polyurethane/Polyethylene Foam Sheets and Strips

These dual-material foam sheets and strips have ultra-soft polyurethane foam on one side and chemical-resistant polyethylene foam on the other. They are widely used in packaging applications to absorb shock and damp vibration.

Super-Cushioning Polyethylene
Foam Sheets and Strips

Also known as Ethafoam.

Food Industry Super-Cushioning
Polyethylene Foam Sheets

Made of FDA-listed materials, these polyethylene foam sheets are often used as packaging for food products to absorb shock and damp vibration.

Extra-Tough Super-Cushioning
Polyethylene Foam Sheets and Strips

These sheets and strips are made of cross-linked polyethylene, so they are stronger and more chemical resistant than other types of polyethylene foam.

Tear-Resistant Super-Cushioning EVA Foam Sheets

Often used as padding in helmets, gloves, and boots, this super-strong EVA foam absorbs shock and resists tearing better than other types of foam.

Ultra-Tough Super-Cushioning Ionomer Foam Sheets

Exceptionally strong, this lightweight ionomer foam offers excellent resistance to impact, UV light, and water. It stands up to wear caused by rubbing and scraping and is often used on bumpers and buoys.

Super-Cushioning Polyurethane
Foam Cords and Circles

Use these flexible polyurethane foam cords and circles to cushion narrow spaces, such as channels and gaps.

Super-Cushioning Foam Egg-Crate Sheets

Super-Cushioning Foam U-Channels

The open top allows these foam U-channels to slide over and cushion an edge.

Super-Cushioning Foam Half Rounds

Use these foam half rounds as a cushioning bumper.

Super-Cushioning Foam Cubed Sheets

Also called plucking foam, these scored foam sheets allow you to pull out individual cubes for custom-shaped packaging.

Super-Cushioning Foam Mesh Sheets

There are hundreds of cushioning pillows in every foot of these pliable mesh sheets. They're often used as a protective liner in drawers and cabinets and anywhere a nonskid surface is required.

Multipurpose Foam

Multipurpose Neoprene Foam Sheets and Strips

In addition to having good resistance to water, sunlight, and oxidation, these neoprene foam sheets and strips resist swelling when they come into contact with oil.

Fabric-Covered Multipurpose Neoprene Foam Sheets

Just like the material found in wetsuits, these neoprene foam sheets are encased in nylon fabric for additional protection from wear caused by rubbing and abrasion.

Ultra-Weather-Resistant EPDM Foam Sheets and Strips

Made of EPDM foam, these sheets and strips have the best resistance to water, sunlight, and oxidation of all the foam we offer.

Fabric-Faced Wear-Resistant
Natural Gum Foam Sheets

The original mouse pad material. These natural foam rubber sheets have a crisscross-textured skin on one side for a nonslip gripping surface and a layer of polyester fabric on the other side that allows objects to smoothly slide across it.

Wear-Resistant Natural Gum Foam Sheets and Strips

Because this natural rubber foam readily bounces back to shape after compression, it’s a good choice for repetitive sealing applications, such as on doors.

Light Duty Blended EPDM Foam Sheets and Strips

EPDM is blended with neoprene and SBR to create a general-purpose foam that offers good resistance to water and wear.

Ultra-Conformable Light Duty
Vinyl Foam Sheets and Strips

These vinyl foam sheets and strips are so conformable that once they're compressed they won't fully spring back. Use them to fill gaps and seal uneven surfaces.

Multipurpose Blended Neoprene Foam Tubes

Neoprene is blended with EPDM and polyethylene for foam tubes that offer good resistance to water, sunlight, and oxidation.

Ultra-Weather-Resistant EPDM Foam Tubes

These EPDM foam tubes have the best resistance to water, sunlight, and oxidation of all the foam tubes we offer.

Ultra-Weather-Resistant EPDM Foam Cords

Made of EPDM, this foam has the best resistance to water, sunlight, and oxidation of all the foam we offer.

Multipurpose Neoprene Foam Cords

These neoprene foam cords stand up to water, sunlight, and oxidation, plus they resist swelling when they come into contact with oil.

Light Duty Weather-Resistant Santoprene Foam Cords

An economical alternative to neoprene foam, these Santoprene foam cords stand up to water, sunlight, and oxidation but lack oil resistance.

Oil-Resistant Buna-N Foam Sheets and Strips

Flame-Retardant Oil-Resistant Blended
Buna-N Foam Sheets and Strips

This foam meets UL fire extinguishing specifications. It's made from a blend of Buna-N, neoprene, and vinyl to offer offer good resistance to oil.

Oil-Resistant Buna-N Foam Sheets

Made of Buna-N foam, these sheets offer excellent oil resistance. They also resist fuel and solvents.

Oil-Resistant Blended Buna-N Foam Strips

Made from a blend of Buna-N, neoprene, and vinyl, these foam strips have good resistance to oil.
