About Foam

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.

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 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.

Super-Cushioning Foam

Super-Cushioning Foam Half Rounds

Use these foam half rounds as a cushioning bumper.

Super-Cushioning Polyurethane
Foam Cords and Circles

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

High-Temperature Foam

High-Temperature Foam Rings

Seal and damp vibration in high-temperature equipment with these rings.

Food Industry High-Temperature Silicone Foam Cords

These silicone foam cords meet NSF/ANSI 51 for food equipment materials. Use them to seal and cushion narrow spaces in food service equipment.

High-Temperature Silicone Foam Cords

Seal and cushion narrow spaces in hot environments with these silicone foam cords.

High-Temperature Foam Tubes

Adhesive-Back Bumpers

Press these bumpers into place with the adhesive backing. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. They're comparable to Bumpon bumpers.

Backer Rods

Provide support for sealants in gaps—insert these backer rods into gaps and fill in with sealant.
