natural rubber is more elastic than synthetic rubber
There is natural rubber, made from the latex of the rubber tree (Hevea brasiliensis).There are several manmade rubber compounds, including butyl rubber, neoprene, and nitrile rubber.
No nitrile rubber is a synthetic rubber polymer
When left out in the sun rubber will loose some of its elasticity or crack, the ink will lose some color, and paper will be bleached or become whiter. This occurs because of the action of the ultraviolet light of the sun.
Natural rubber, or gum rubber, is made from latex. A LOT of rubber available today is synthetic, made from petroleum. And a large amount of the gum rubber contains a percentage of synthetic rubber.
Vulcanized rubber is process that changes the properties of natural rubber so that it is more usable for products. Natural rubber hardens rock-solid in freezing temperature and melts into goo in summer heat. For an interesting reprint of a Readers Digest article on the invention of rubber - see the attach link.
According to http://www.koolance.com/technical/cooling101/002.html the specific heat is 1.6 kJ/kgK According to my small pocket technical guide "Gieck Technical Formula's" it's 1.42 kJ/kgK
Only carbon, hydrogen, and oxygen in pure natural latex, but rubber articles of manufacture usually contain other elements to improve the properties of the natural rubber for specific applications. Sulfur and zinc oxide are common additives to rubber.
Mixing natural rubber with nitrile rubber is possible. In fact, it is quite common to mix natural rubber with other kinds of rubbers.
natural rubber is more elastic than synthetic rubber
Natural rubber is created from the sap of the Rubber Tree. In fact, that is the only thing needed from the tree to produce natural rubber.

There is no such thing as a natural rubber, rubber is man made.
There is natural rubber, made from the latex of the rubber tree (Hevea brasiliensis).There are several manmade rubber compounds, including butyl rubber, neoprene, and nitrile rubber.
Rubber trees grow naturally in Brazil in the rain forest. People like to grow specific crops together on farms. The Brazilian rain forest is not a good place for farms. Malaysia was a place where it was possible to create farms for rubber trees. As a result that is where they were planted. The advantage of cultivation of natural rubber in Malaysia is because it is possible.
because humans cannot make synthetic rubber exactly the same as natural rubber.
