Isoprene Rubber Uses

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.

Isoprene rubber uses.

Isoprene is an unsaturated hydrocarbon. Due to its outstanding strength and excellent compression set isoprene rubber is the preferred material for many engineering applications. The largest end use for polyisoprene by far is in tires. The polymerization of isoprene using ziegler catalysts yields synthetic rubber that closely resembles the natural product.

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. Typical uses include anti vibration mounts drive couplings tires springs bearings rubber bands and adhesives. Black loaded polyisoprene finds uses in tires motor mounts pipe gaskets shock absorber bushings and many other molded and mechanical goods. 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.

It is either harvested in the form of latex from rubber trees nr or synthetically produced by polymerization of 1 methyl 1 3 butadiene ir. Isoprene rubber properties and applications. 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. Polyisoprene is a collective name for polymers that are produced by polymerization of isoprene in principle four different isomers can form.

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. The typical working temperature range is 50 c to 100 c.
