Fire Retardant Silicone Sponge No Adhesive - 1/2" Thick x 12"W x 12"L

Made by USA Sealing. EVA is lightweight, yet tough and tear resistant. It is closed cell so it doesnt absorb moisture and is often used for padding inside helmets and cushioning within straps.

Made by USA Sealing. Microcellular Polyurethane has excellent resistance to impact (absorbs shock) and resilient (recovers from compression time and time again), making it an excellent material for long lasting and long-term applications, such as shoes, helmets, devices, and hard to maintain equipment and machinery. Also used for high performance gasketing and sealing.

Buna-N/PVC foam exhibits excellent impact absorption and good chemical resistance properties. Also known as crushed-cell foam, semi-closed foam is highly conformable like an open-cell foam but forms a tight seal and prevents air, water, and fluids from passing through it like a closed-cell foam.

Fire Retardant Neoprene Foam Sheet No Adhesive - 1" Thick x 12" Wide x 24" Long Neoprene is the most commonly used foam material due to its good balance of strength, oil, water, and weather resistance. Common applications include industrial gaskets to seal water, air, dust, and other environmental items, automotive gaskets, and athletic equipment. This neoprene is lighter and easier to compress than other Neoprene foams. It is also UL listed for flame retardance.

EPDM is the most weather resistant foam, with a wide range of chemical compatibility, steam resistance, and good temperature range. Also known as crushed-cell foam, semi-closed foam is highly conformable like an open-cell foam but forms a tight seal and prevents air, water, and fluids from passing through it like a closed-cell foam.
