Rubber foam, also known as cellular rubber, sponge rubber, or expanded rubber, is a versatile class of materials created by introducing gas bubbles into a rubber matrix to form an air-filled cellular structure. These materials combine the inherent elasticity of rubber with the lightweight, insulating, and cushioning properties derived from their porous structure.
