Polyisoprene elastomers (IR, isoprene rubber, polyisoprene rubber) are synthetic, predominantly stereoregular polymers that closely resemble natural rubber in molecular structure as well as in properties. Polyisoprene elastomers are produced via solution polymerization using stereospecific catalysts. Chemically, natural rubber is pure cis-1,4- polyisoprene, while commercial grades of synthetic cis-1,4 isoprene rubber (cis-1,4 IR) have greater than 95% cis-1,4-polyisoprene content. trans-1,4-Polyisoprene (trans-IR) and 3,4-polyisoprene can also be produced synthetically, but are of minor commercial importance.
Polyisoprene elastomers are currently used in a variety of end-use applications requiring good resilience, low water swell, high gum tensile strength, good tack and high hot tensile strength. The largest end use for polyisoprene by far is in tires. Black-loaded polyisoprene finds uses in tires, motor mounts, pipe gaskets, shock-absorber bushings and many other molded and mechanical goods. Gum polyisoprene compounds are used in rubber bands, cut thread, baby bottle nipples and extruded hoses, along with other such items. Polyisoprene that is mineral filled finds applications in footwear, sponges and sporting goods. Other important uses include medical and health applications, and sealants and adhesives. Of all the applications, medical and health applications have recorded the fastest growth.
