When a foaming agent is introduced into rubber during its production process, the result is a type of elastomer known as cellular rubber. It is a softer sponge-like elastomer whose body features an air-filled matrix. These types of elastomers are far more compressible than their standard solid counterparts, hence why they are often referred to as “sponge” rubber. This particular closed cell sponge rubber is a blend of different elastomer types. The material of this closed cell blended rubber uses SBR rubber, EPDM material, and closed cell neoprene in its makeup. It inherits the traits of its parent materials in moderate levels. The main distinguishing feature about this cellular rubber is that it is available with a backing of pressure sensitive adhesive, also known as PSA.
Sponge Sheet with PSA: Each of these closed cell sponge sheets feature a white film on one side. It is a double-coated rubber base polyester film that contains pressure sensitive adhesive (PSA). The adhesive helps the sheet stick onto surfaces whenever the application requires a part to stay in place. In order to apply the cellular rubber sheet onto a surface, simply peel away the white protective film to expose the sticky adhesive beneath it and place the sheet onto the target area.
Moderate Weather Resistance: This PSA-backed closed cell sponge rubber benefits from the presence of EPDM material in its body. The defining characteristic of EPDM rubber is an enhanced resistance against outdoor weathering effects such as UV rays and ozone. It is the ideal elastomer whenever a rubber part is needed for the outdoors. Due to the presence of EPDM in this blended cellular rubber, it has a moderate degree of outdoor weather resistance from the EPDM used to make it. It has a fair level of resistance to UV rays, but tends to resist ozone at a superior rate.
A Durable Sponge Rubber: As a direct benefit from the SBR rubber used to make it, this adhesive-backed closed cell sponge rubber exhibits a better degree of physical durability than other sponge rubber counterparts that do not have SBR in their makeup. SBR is known for its superior physical strength and resistance to physical abrasions. 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: Light to moderate contact with oil will not pose a problem to this sponge rubber sheet thanks to the presence of closed cell neoprene in its material makeup. 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. That oil-resistance is still present in this cellular rubber, although in a more moderate form. This PSA-backed sponge sheet is not intended for heavy contact with oil.
