About Foam

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 Half Rounds

Use these foam half rounds as a cushioning bumper.

Multipurpose Foam

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.

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.

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.

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.

High-Temperature Foam

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 Rings

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

High-Temperature Foam Tubes

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.

Earplugs

Protect your hearing in loud environments.

Foam-Forming 3D Printer Filaments

Print these polypropylene filaments into filters, gaskets, and other lightweight, foam-like parts that let air and gas pass through but repel water.
