Foam rubber sponge is a type of rubber product that feels spongy to the touch and is more compressible when compared to standard solid rubber. It has a cellular structure that is apparent in its texture. One variation of this is closed cell rubber. The closed cell types of sponge rubber are great for high-pressure applications where superior compression strength is needed. Additionally, its cellular structure is not as visible as it is in its open cell counterpart. This particular type of closed cell sponge rubber is made using EPDM material. EPDM rubber is a very popular type of synthetic elastomer that is great for use in outdoor conditions. It has a superior level of resistance against common hazards such as UV rays and ozone. As a result, this closed cell EPDM sponge rubber is excellent for any application that requires outdoor usage.
High Compressive Strength: Closed cell rubber is a bit different from its open cell counterpart in terms of compressive strength. While open cell sponge rubber can rebound back to its original shape very quickly, closed foam rubber sponge takes a bit longer to do so. This allows the closed cell EPDM sponge rubber to handle high- pressure applications at a better rate, making it more durable.
Perfect for the Outdoors: The excellent ability of this closed cell rubber to operate in the outdoors is all thanks to the compound of EPDM rubber in its structural makeup. It has an excellent level of resistant to both UV rays and ozone. Outdoor factors like UV and ozone may not damage a material immediately, but they can definitely degrade a material over time. The EPDM compound in this sponge rubber allows it to remain exposed to the elements for extended periods of time. This is the primary reason why EPDM material is a popular elastomer to use in applications such as window sealing on vehicles and homes.
Good Moisture Resistance: One of the key benefits about closed cell rubber is that is can resist moisture easily. It does not absorb fluids or general moisture very easily. This is thanks to the nature of the structure of the closed cell material itself. It prevents water and other liquids from seeping through immediately. Instead, it keeps the moisture on its surface for longer periods of time. One could even wipe water droplets off the surface of this material if they wanted to! This feature makes this type of EPDM closed foam rubber sponge ideal for use as a sealing or gasketing option.
