About Foam

Lightweight UV-Resistant PET Foam Cores

When exposed to UV rays, these cores won’t become brittle or break down. Use them to add stiffness to composite sandwiches that may be used outdoors without adding a lot of weight.

Stiff PVC Foam Cores

Add stiffness to composite sandwiches without adding a lot of weight.

Thermal Insulation

Impact-Resistant Low-Temperature
Rigid PVC Foam Insulation Sheets

Made of rugged PVC foam, these rigid sheets absorb impact and restrict the absorption of water, air, and gas. Use in applications with operating temperatures below 32° F.

Moisture-Resistant Low-Temperature
Rigid Polystyrene Foam Insulation Sheets

These sheets resist the absorption of water, air, and gas and are widely used in cold-storage and packaging applications.

Crack-Resistant Rigid Polyimide Insulation Sheets

Even when subjected to heavy compression, these rigid polyimide sheets won't crack.

Abrasion-Resistant Silicone Foam Insulation Sheets

The fiberglass facing on these flexible silicone foam sheets protects against highly abrasive conditions and resists tearing.

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.

Economical Flexible Polyethylene Foam Pipe Insulation

Less flexible than rubber foam, this insulation restricts absorption of water, air, and gas. It is typically used in plumbing applications

Flexible Rubber Foam Pipe Insulation

Soft and easy to install, this insulation restricts absorption of water, air, and gas. It is often used on cold and hot water lines and refrigeration lines.

Foam

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.

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 Blended Neoprene Foam Tubes

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

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 Tubes

High-Temperature Silicone Foam Cords

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

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.
