About This Product

These closed cell rubber sponge sheets are made from a combination of neoprene and SBR (styrene butadiene rubber). Sponge rubber is also referred to as cellular or foam rubber. It takes these names because numerous air pockets are dispersed throughout the rubber material, making it softer and easier to compress than a piece of solid rubber. Because these air pockets excel at trapping and dissipating kinetic energy, rubber sponge demonstrates great shock absorbency and sees use in applications for energy absorption and protective rubber padding. These air pockets also ensure that sponge rubber transmits heat at a slower rate compared to solid rubber, making it a suitable material for heat insulation. Due to the sealed nature of the air pockets in closed cell sponge rubber, this material has a higher compressive strength than open cell sponge and retains its shape more effectively. This attribute of closed cell sponge makes it preferable to open cell sponge in padding applications where a rubber piece must maintain its structure while still absorbing kinetic energy. The isolated air pockets in closed cell rubber also make the material far less porous than open cell, preventing the material from absorbing water. Combined with the water-resistant nature of SBR and neoprene rubber materials, this closed cell blended rubber often sees use in aquatic and gasketing applications.

    Q:Is this good as a cover over metal hatch (entrance to cellar) in my front yard? Looking to prevent water seepage along the edge of metal hatch and insulation in winter
    by|Nov 26, 2023
    1 Answer
    Answer This Question

    A:  Hello! Thank you for reaching out! While the Closed Cell Sponge Rubber Blend provides excellent insulation, it may not be the best choice for preventing water seepage, as sponges tend to absorb water. For your specific need to cover a metal hatch and prevent water seepage, I recommend considering a solid rubber option. The Rubber-Cal EPDM Commercial Grade 60A is a great choice. It's durable, ozone-resistant, and UV-resistant, making it suitable for outdoor use. Its solid structure will help prevent water seepage and provide insulation during winter. If you have any more questions or if there's anything else we can assist you with, please feel free to let us know. We're here to help you find the right solution for your needs. Best regards, Robert Morris Rubber-Cal, Inc.

      Q:would this product hold up to weight being placed on it and not collapsing?
      by|Sep 2, 2023
      1 Answer
      Answer This Question

      A:  Hello Density, Thank you for your question regarding the load-bearing capacity of the Rubber-Cal Closed Cell Sponge Rubber Blend Black Foam Rubber Sheet. We appreciate your interest and are here to provide you with the necessary information. To address your inquiry, it's important to note that the Rubber-Cal Closed Cell Sponge Rubber Blend Foam Rubber Sheet is primarily designed for applications where cushioning and insulation properties are required. However, it is not suitable for supporting heavy loads or weight-bearing applications. This foam rubber sheet is essentially a foam material, and as such, it can achieve full compression with very little force. It is not designed to withstand significant weight or pressure without collapsing or compressing under the load. If you require a material that can support weight and provide structural stability, we recommend considering one of our solid sheet rubber products. These solid rubber sheets are specifically engineered to handle load-bearing applications and can provide the necessary support and durability. If you have specific weight-bearing requirements or need assistance in selecting the right material for your project, please feel free to provide more details about your application, and we would be happy to recommend a suitable product from our range of rubber sheets. Thank you for considering Rubber-Cal, and we're here to assist you in finding the right solution for your needs. If you have any more questions or require further information, please don't hesitate to reach out. Sincerely, Robert Morris Rubber-Cal, Inc.

        Q:Is the black rubber sheets waterproof?
        by|Aug 25, 2023
        1 Answer
        Answer This Question

        A:  Hello Frankly, Thank you for your question regarding the waterproof properties of the Rubber-Cal Closed Cell Sponge Rubber Blend Black Foam Rubber Sheet. We're here to provide you with accurate information about this product. To address your inquiry, the closed-cell sponge rubber blend used in these foam rubber sheets is not considered fully waterproof. While closed-cell foam does have a degree of water resistance due to its closed-cell structure, it is not completely impervious to water. Closed-cell foam can absorb a small percentage of liquids, typically ranging from about 3 to 5% of its volume. This means that while the foam rubber sheets can resist some water absorption due to their closed-cell design, they are not entirely waterproof. Depending on the specific application and exposure to moisture, they may offer some degree of protection against water ingress. However, if you require a material that is completely impermeable to water, you may want to explore other options. If you have specific requirements for water resistance or waterproofing, please feel free to share more details about your intended use. This will help us provide you with recommendations for the most suitable materials for your needs. If you have any further questions or need assistance with selecting the right material for your project, please don't hesitate to reach out. We're here to assist you in finding the best solution for your application. Thank you for considering Rubber-Cal, and we look forward to helping you with your foam rubber sheeting requirements. Sincerely, Robert Morris Rubber-Cal, Inc.

          I purchased this product to use as a sealer around my pop-up camper. We are now in our monsoon season and so far, not one drop of water. I would highly recommend this product due to its density and sealing properties.
