Synthetic and Natural Rubber Essay -- Comparison Material Rubber

Synthetic and subjective synthetic refugeAbstractRubber is an important resource with a wide variety of applications. It can be obtainednaturally from the galosh tree, Hevea brasiliensis. It can also be synthesized from rock oil andnatural gas. Both natural and synthetic rubbers have their own advantages and disadvantages.Natural rubber is made up the linear chain polymer, cis-l,4-polyisoprene. Styrene-butadienerubber (SBR) is the more or less common synthetic rubber. It is a random copolymer of styrene andbutadiene and has good tangible properties once it has been strengthened through vulcanization.IntroductionRubber is an elastomer that can be obtained naturally from certain trees or synthesizedfrom petroleum and natural gas. 1 It is a priceless resource that is commonly used in tires,machine belting, wire insulation, and clothe soles. Rubber is created naturally, most commonly bythe rubber tree, Hevea brasiliensis .1 in that respect are many different types of synthetic rubberincluding isoprene, butadiene, polysulfides, polychloroprene, nitrile rubber, and styrenebutadienerubber. 3 there are advantages and disadvantages of both synthetic and naturalrubber.ResultsHevea trees are indigene to the Amazon region, but were brought to Asia, which is now thelargest producer of natural rubber. 1 Natural rubber is obtained by a process called tapping. 2 Aknife is used to guard a shallow cut in the tree to allow rubber-base paint to flow freely and be collected in acup.2 A single tapping yields about 50 grams of rubber and usually occurs once every(prenominal) two days.2 Natural rubber can be produced at a rate of about 1 ton of rubber per acre per year. 2Natural rubber is the linear chain polymer, cis-l,4-polyisoprene. The polymer is ... ...lant Products. 7 Jan.1998. 29 July 2008.8 Rodgers, Brendan, Donald S. Tracey, and Walter H. Waddell. Biosynthesis of naturalrubber. digital image. EBSCOhost.
