Rubber-Cal Closed Cell Rubber Neoprene - 1/8 Thick x 39 x 78

These neoprene sheets consist of closed cell rubber sponge. Closed cell sponge rubber is created by distributing gas through the rubber during production, creating sealed air pockets within the rubber material. Due to these air pockets, closed cell neoprene sponge is softer, more compressible, and superior at absorbing energy compared to solid rubber.
