Natural Rubber Made Tires

60 of rubber used in the tire industry is synthetic rubber produced from petroleum derived hydrocarbons although natural rubber is still necessary for the remaining 40 synthetic elastomers deform under stress and return to their original shape when the stress is removed hysteresis this property is extremely valuable for the manufacture of high grip tires.
Natural rubber made tires. Continental has already produced the first test tires for passenger cars and trucks. Clearly then there are things which distinguish the two products as no matter how great science and technology is today it cannot perfectly replicate natural rubber. The rest is made up of metal. Natural rubber one of the primary materials in tires is produced from the latex of para rubber trees 1 and currently about 90 of its plantations are concentrated in southeast asia.
The rubber tree grows deep in the hot damp forests of southeast asia africa and south america the world s rubber belt when these trees grown on rubber plantations mature an incision is made in the trunk of the tree to collect the latex sap and let the tree live on. The two main synthetic rubber polymers used in tire manufacturing are butadiene rubber and styrene butadiene rubber. Tires made of the synthetic rubber lose 30 percent less mass than equivalent tires made of natural rubber. In the future continental s long term taraxagum project will be to supply natural rubber from dandelion plants which can be used for the production of two wheel passenger car or commercial vehicle tires as well as other vehicle parts made of natural rubber.
On the other hand the design of aircraft tires necessitates that they be made completely out of natural rubber. On top of that the synthetic tires have only half the tread loss. It is especially good for tear and fatigue crack resistance. The rubber itself and a reinforcing filler.
Today tires consist of about 19 percent natural rubber and 24 percent synthetic rubber which is a plastic polymer. These rubber polymers are used in combination with natural rubber. And while synthetic tires are derived from petroleum based products there is still a large market for tires made out of natural rubber. The most common form is natural rubber which is the latex sap found in the bark of the rubber tree.
Natural rubber provides specific performance characteristics to tires. In tire manufacturing there are usually four main types of rubber used.
