Synthetic and Natural Rubber Essay -- Comparison Material Rubber

Synthetic and born(p) Rubber liftRubber is an important resource with a wide variety of applications. It tail be obtained inbredly from the natural rubber tree, genus Hevea brasiliensis. It tooshie also be synthesized from petroleum andnatural gas. Both natural and synthetic rubbers have their birth advantages and disadvantages. inhering rubber is made up the linear chain polymer, cis-l,4-polyisoprene. Styrene-butadienerubber (SBR) is the most common synthetic rubber. It is a random copolymer of styrene andbutadiene and has skinny physical properties at 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 valuable resource that is commonly utilize in tires,machine belting, telegram insulation, and shoe soles. Rubber is created naturally, most commonly bythe rubber tree, Hevea brasiliensis .1 There be many different types of synthetic rub berincluding isoprene, butadiene, polysulfides, polychloroprene, nitril rubber, and styrenebutadienerubber. 3 There are advantages and disadvantages of both synthetic and naturalrubber.ResultsHevea trees are native 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 make a sh provide cut in the tree to allow latex to flow freely and be collected in acup.2 A single tapping yields about 50 grams of rubber and usually occurs once every 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.
