Closed Cell Rubber - Neoprene. Synthetic rubber can be made from the polymerization of a wide range of monomers including isoprene (2-methyl-1 ,3-butadiene), 1,3-butadiene, chloroprene (2-chloro-1 ,3-butadiene), and Natural rubber is still an important industrial polymer, but it now competes with a number of synthetics, such as styrene-butadiene rubber and butadiene rubber, which are derived from by-products of petroleum and natural gas. Neoprene is a synthetic rubber formed by the free radical addition polymerization of chloroprene. Their catalyst, an organoaluminum compound coupled with a transition metal, led to the development of synthetic rubbers with a structure closely resembling natural rubber. How these materials are structured in turn affects their properties and performance in plumbing jobs. ; They are more lightweight and cost less than regular containers.
