A sheet of rubber sponge, also referred to as rubber foam, is known for its good resistance against environmental conditions and chemicals, making it useful in applications related to weather or sealing. Materials such as a neoprene foam gasket are developed and put into everyday products since this rubber is reliable and durable. With varieties in the nature of these neoprene products—open or closed cell sponge rubber—out there, give customers many choices and advantages.
Closed Cell Rubber – EPDM
- Thermal Insulation: Depending on whether you buy an open or closed cell rubber sponge rubber, foam elastomers can provide good padding. This insulating feature keeps cold or hot temperatures in while keeping the unwanted thermal condition out. Rubber sponge material is very good at maintaining and regulating the temperature of the air around it. The elastomer has even been utilized for insulation ducting thanks to its ability to insulate. An example of these applications would be refrigerators where sealing is vital. A product made with rubber sponge will not allow heat or moisture to pass through.
- Weather and Ozone Resistant: Since rubber sponge material is good for weather sealing, it is only a given main requirement that the elastomer be able to withstand weather or ozone damages. Lucky for us, a neoprene foam gasket provides good resistance to these kinds of threats. The most common environmental hazards are UV rays from the sun, ozone in the air, and moisture in the form of rain or snow. UV rays and ozone tend to cause cracks and discoloration in most other rubbers. For example EPDM rubber foam can be exposed to their elements thanks to its ability to keep its integrity in the sun. Water will not be able to cause any mold damage. In fact, closed cell sponge rubber is often used in aquatic applications because it does not allow water to pass through it. Ultimately, a rubber product is a trustworthy product to use in the outdoors since we know that atmospheric conditions will not affect it in the short-run.
Open Cell Rubber – EPDM
- Operating temperature range from -40° F to 160° F
- Easy to roll up for transportation and storage purposes
- Pressure sensitive adhesive backing can be applied upon request
- The cellular texture of the open cell rubber is visible on the surface
Excellent Compressibility: This EPDM rubber foam is among the most compressible products currently available. The cellular composition of this open cell rubber material is the secret behind its ability to compress. The cell structure is composed of tiny air pockets that have gaps in between them. When force is applied to the surface of the EPDM sponge, these air pockets will close in on themselves. The source of the pressure will also not face any resistance due to the soft nature of open cell sponge. The EPDM foam sheet will maintain its compressed form as long as the object applying the pressure remains.
Fast Recovery: The open cell EPDM has the ability to revert back to its original shape after compression. When the source of pressure is removed from the open cell rubber sheet’s surface, the air pockets within its cellular composition will revert back to their original shape. This helps the EPDM rubber foam maintain a working lifespan suitable to long-term use in applications that require constant compression.
Closed Cell Rubber – EPDM – 39″ x 78″
- Ability to Endure Everyday Chemicals: One always has to be very careful whenever chemicals are involved in an application. Some chemicals are very damaging to ordinary natural or recycled rubbers. However, a rubber sponge sheet will be able to resist most light general chemicals that come into contact with it. This allows the elastomer to be used in general sealing roles without fear of the foam product failing and deteriorating. Unlike other foams, longevity makes sheet rubber foam a good candidate for lots of sealing and gasket applications.
- Great Bounce Back: Closed cell rubber sponge rubber has good compressive strength and is flexible. Since sponge elastomers also have a fairly good resistance in dynamic uses, they are excellent as seals in industrial equipment and machinery. Its durability and flexibility allows this rubber sponge sheets to be used in applications that require a good life cycle from the rubber.
- Sound Absorption: Open cell rubber has good sound absorption. Because of its structure, an open cell rubber sheet can provide a customer with good sound dampening. Hence the less expensive, blended, version of this cellular rubber can be used in structural applications.
As you can see, there are many benefits to using a rubber sponge sheet. Whether the material is used as an outdoors neoprene foam gasket for its good ozone and weather resistance, or as an open or closed cell sponge rubber used for indoor sealing, this elastomer gives the customers flexibility. The universality of this rubber reduces the need for multiple variations of materials to be inventoried or specked-out!
Closed Cell Rubber – Blend
- Temperature Range: -40 F to +200 F
- Durometer rating of 20-25 Shore C
- Sheets available in size of 39in by 78in
- Ideal for use in shock absorption and gasket related applications
- A versatile blend of closed cell sponge available at affordable rates
A Durable Sponge Rubber: As a direct benefit from the SBR rubber used to make it, this closed cell sponge rubber possesses a good degree of physical durability. SBR is known for its superior physical strength and resistance to physical abrasions. It is the reason why SBR is so popular for use in vehicle tires, which are expected to endure harsh physical conditions on a daily basis. Although cellular rubber tends to be a softer material overall, especially when compared to its regular solid rubber counterparts, it is still durable enough to handle some moderate level physical abrasions.
Resists Light Oil Contact: Thanks to the presence of closed cell neoprene rubber in this elastomer; it will be able to resist light to moderate amounts of oil. Neoprene is a synthetic rubber that is commonly used for oil-related applications. By itself, neoprene is very good at resisting the otherwise damaging effects of various oils and greases. In this blended cellular rubber, that quality is there but in a more moderate form. It can handle light oil contact with ease, but it should be noted that it does not hold up very well against heavy oil contact.
