Chloroprene Rubber is normally abbreviated to CR, but more commonly known as Neoprene and is a synthetic Polymer. Rubber Sheeting described as Neoprene will be a blend of polymers including a percentage of Chloroprene. Specification Grades will container higher levels of Chloroprene than commercial grades. Typically used in applications where Flame Retardency and Ozone Resistance are required. Neoprene Rubber Sheeting is available if a range of hardness's and rubber roll sizes to meet your requirements.
