Cellular rubber is a type of rubber material that is formed when a foaming agent is introduced into rubber while it is being produced. The process results in an elastomer whose body features an air-filled matrix. The resulting rubber is ultimately more compressible than normal solid rubber counterparts. This particular closed cell sponge rubber is a blend of different elastomer types. The material of this closed cell blended rubber uses SBR rubber and closed cell neoprene in its makeup. The result is a sponge rubber product that is affordable and durable. It inherits the traits of its parent materials in moderate levels. It is a black colored cellular rubber that works as a good general-purpose elastomer material.
Moderate Weather Resistance: This closed cell sponge rubber benefits from the presence of Neoprene material since each sponge sheet is composed of Neoprene and SBR. A characteristic of Neoprene rubber is its good resistance to outdoor weathering effects such as UV rays and ozone. As a result, it is often employed wherever a rubber part is needed for the outdoors. This blended cellular rubber possesses a moderate degree of outdoor weather resistance.
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.
