Neoprene sheets are also valued for their intense temperature range and resistance. This unique sheet neoprene compound gives the rubber material a moderate resistance to oils, chemicals, and many damaging effects of weather. This 1” neoprene is the thickest option available and works best in high-stress physical applications. Our neoprene sheet is actually a powerful compound made up of SBR and chloroprene rubber (CR) to inherit the strengths of both synthetic rubbers.
