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.

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.

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.

Super-Cushioning Polyurethane
Foam Cords and Circles

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

Multipurpose Neoprene Rubber Rods

The cylindrical shape fits into channels and other narrow spaces for sealing and cushioning.

Weather-Resistant EPDM Rubber Rods

Resistant to sunlight, ozone, and water, these rods are sized to seal narrow spaces such as channels.

Nonporous Alumina Ceramic Rods and Discs

Tight-Tolerance Nonporous Alumina Ceramic Rods

Easy-to-Machine Alumina-Bisque
Ceramic Rods and Discs

Often used to create prototype components, these ceramic rods and discs come semi-fired so they can be machined using conventional metalworking tools.

Ultra-High-Temperature
Easy-to-Machine Alumina Ceramic Rods

Low Thermal Expansion
Alumina-Silicate Ceramic Rods

Thermally Shock-Resistant Mullite Ceramic Rods

Used in prototypes, insulators, and machine tooling, these mullite ceramic rods won’t deform or crack when exposed to extreme temperature changes, high heat, or stress.
