Use
The primary use of isoprene is the manufacture of polyisoprene, or ‘synthetic’ natural rubber, which is subsequently used to make tires. Other major uses of isoprene include the production of styrenic thermoplastic elastomer block copolymers (styrene–isoprene–styrene) and butyl rubber (isobutene– isoprene copolymer). Isoprene is also used to manufacture other chemicals, intermediates, and derivatives, which are subsequently used to manufacture vitamins, pharmaceuticals, flavorings and fragrances, and epoxy hardeners.
