Isoprene Rubber Uses

Butyl rubber made from isobutene with a small amount of isoprene using aluminum chloride initiator has outstanding impermeability to gases and is used in inner tubes.

Isoprene rubber uses. Polyisoprene polymer of isoprene c 5 h 8 that is the primary chemical constituent of natural rubber of the naturally occurring resins balata and gutta percha and of the synthetic equivalents of these materials. Isoprene or 2 methyl 1 3 butadiene is a common organic compound with the formula ch 2 c ch 3 ch ch 2 in its pure form it is a colorless volatile liquid. Black loaded polyisoprene finds uses in tires motor mounts pipe gaskets shock absorber bushings and many other molded and mechanical goods. The typical working temperature range is 50 c to 100 c.

Depending on its molecular structure polyisoprene can be a resilient elastic polymer as in the case of natural rubber and isoprene rubber or a tough leathery resin as in. Isoprene is an unsaturated hydrocarbon. Gum polyisoprene compounds are used in rubber bands cut thread baby bottle nipples and extruded hoses along with other such items. Cis 1 4 polyisoprene which is also called isoprene rubber is a major ingredient of natural rubber trans 1 4 polyisoprene is a major ingredient of gutta percha annual worldwide production of polyisoprene was 13 megatonnes in 2007.

The largest end use for polyisoprene by far is in tires. Due to its outstanding strength and excellent compression set isoprene rubber is the preferred material for many engineering applications. The polymerization of isoprene using ziegler catalysts yields synthetic rubber that closely resembles the natural product. It is produced by many plants and animals including humans and its polymers are the main component of natural rubber.

Typical uses include anti vibration mounts drive couplings tires springs bearings rubber bands and adhesives. Polyisoprene is a collective name for polymers that are produced by polymerization of isoprene in principle four different isomers can form.
