The unique mix of SBR and rubber chloroprene that makes up Rubber-Cal’s Neoprene sheet rubber gives it great resistance to many substances that can easily degrade other synthetic rubber materials. The result is a smooth and solid black rubber sheeting that is highly desired for commercial and industrial applications.While other rubber materials may degrade quickly under intense physical conditions, this neoprene rubber is designed to endure. No need to worry about high temperatures or heavy abrasions damaging the sheet rubber product; this 1/4" neoprene is one of the slightly thicker options available and works best in high-stress physical applications.
