APG 0756CCFR is a type of closed cell sponge made of neoprene, a synthetic rubber material. It is a medium density sponge with a black color and has been treated to be fire retardant. This makes it useful for applications where fire safety is a concern, such as in the construction or automotive industries. The closed cell structure of the sponge means that it is resistant to water and air, making it suitable for outdoor or underwater use.
