About Foam

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.

Super-Cushioning Polyurethane Foam
Sheets, Bars, Cubes, and Strips

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

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.

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.

Shock-Absorbing Resilient
Polyurethane Foam Sheets and Strips

Often used for impact pads, gaskets, and enclosure seals, these polyurethane foam sheets and strips absorb shock better than other resilient foam.

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.

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.

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 Cubed Sheets

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

Super-Cushioning Foam Egg-Crate Sheets

Static-Control Super-Cushioning
Polyurethane Foam Sheets

Cushion electronic components from impact as you protect them from electrostatic shocks during shipping and storing.

Antistatic Super-Cushioning
Polyurethane Foam Egg-Crate Sheets

These polyurethane foam egg-crate sheets divert static electricity to protect sensitive equipment from damage.

Super-Absorbent Foam

Similar to a sponge, this open-cell foam absorbs and holds up to 30 times its weight in liquid.

Foam Material Sample Packs

EMI/RFI-Shielding Gaskets

These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems.

EMI/RFI-Shielding Gaskets for Data Connectors

Fit these gaskets over connectors that plug in to your enclosure to absorb interference and prevent signal problems.

Heating, Venting, and Air Conditioning

Vibration Damping Sheets

Install these adhesive-back sheets to reduce noise from vibrating surfaces, such as duct and equipment housings.

Sound-Absorbing Sheets

Use these sheets to quiet noisy areas and line machine enclosures. They’re made of humidity-resistant polyurethane foam and have a smooth, easy-to-clean facing.

Contoured Sound-Absorbing Sheets

Also known as egg crate, these sheets have peaks and valleys that absorb more sound at higher frequencies than flat-surface sheets. Use them to quiet noisy areas and line machine enclosures. Sheets are made of humidity-resistant polyurethane foam.

Heat-Reflecting Sound-Absorbing Sheets

The foil facing reflects heat. Use these sheets to quiet noisy areas and line machine enclosures. They’re made of humidity-resistant polyurethane foam.

Oil-Resistant Sound-Absorbing Sheets

Either a urethane or polyester coating protects these humidity-resistant polyurethane foam sheets from oil exposure. Use them to quiet noisy areas and line machine enclosures.

Sound Barrier Sheets

Reflect sound and block noise from traveling to other parts of your facility.

Polyurethane Foam Insulation
Sheets with Perforated Facing

The perforated vinyl facing allows moisture to evaporate and resists cracking and fading. These flexible sheets are good for insulating large enclosures.

Foam Casting Compounds

Create lightweight molds with these two-part compounds.

Expanding Foam Fill

Create custom-fitted packaging for products of almost any size or shape. When activated, foam packs expand to fill the space around items.

Tape

Foam Mounting Tape Sheets

Cut these sheets to the shape you need for a custom fit.

Foam Mounting Tape Shapes

Tape is cut into convenient discs and rectangles.

Foam Mounting Tape

Used to mount panels, signs, and dispensers, this foam tape absorbs shock and provides high strength holding power on rigid surfaces.

Sealing Tape for Large Gaps and Voids

An alternative to caulk and rubber sealants, this tape comes compressed and gradually expands to fill large gaps and voids.

Shock-Absorbing Low-Friction UHMW Tape

Reduce noise and vibration in chutes, bins, and similar delivery systems with this UHMW-faced foam tape.

Scratch-Free Scouring Blocks

Aggressive cleaning without scratching, this scouring block is made of a chemical-resistant foam block with a handle.
