Flame Resistance CR Foam Sheet Sound Absorption Neoprene Rubber Roll For Automotive
Closed-cell neoprene sponge rubber is an elastomer perfect for use in applications that involve the presence of oils, greases, and moderate outdoor exposure. Also known as neoprene foam or cellular neoprene rubber, this material is made by using a foaming agent to create a structure filled with air pockets.
This particular type of closed cell sponge rubber is made using neoprene rubber. The neoprene compound used in its makeup gives the foam rubber a better degree of resistance to oil and ozone. Neoprene foam rubber is the ideal type of material to use as a seal or gasket for any application that will involve such conditions.
Oil Resistance: Neoprene rubber is widely used in tasks that require a moderate presence of oils and greases. It offers a good level of resistance to those substances. Other material can be stained or damaged by oil, but neoprene will stand up to such corrosive elements. This trait is still present when the neoprene comes in cellular rubber form.
Weathering Resistance: In addition to oils and greases, neoprene can also operate in the outdoors. It can resist the degrading effects of UV rays, ozone, and even moisture from rainfall. It is very strong when it comes to UV rays. UV rays can cause damage such as discoloration in some materials, but will have a very hard time doing so with this foam rubber material.
A big benefit of having a closed cell sponge rubber in wet and moist conditions is that the closed cell structure will not soak up any of the moisture. Water will be prevented from seeping into the material and causing any damage.
